The Calibration Lamp Systems (CLS) serve as calibration units for the NTT instruments. Two systems are installed on the NTT; System A for IRSPEC, and System B for EMMI. System A has three lamps and a black body on the sphere (no wheel unit); System B has seven lamps on the wheel and three lamps on the sphere.
A third system, similar to System B, will be installed on the 2.2m telescope for calibration of EFOSC.
The main components of the system are:
The lamps on the sphere are switchable via a dedicated serial link (System B), or an RS232 link (System A). The light from these lamps is fed directly into the sphere. For the lamps on the wheel unit (System B only), the light is carried over to the sphere via an optical fiber. The selection of a function (switching a lamp, shutter or positioning the fiber) can be done via an integrated control panel in the control unit, or under software control via the I/O boards 5 and 6 in the Autoguider Rack (System B) or via board 5 in the AGR (System A).
The tables below give an overview of the different lamps used in the system, and the technical specification for each.

The optical fiber used on the EMMI probe is a fiber bundle 2.5mm diameter and 27m long; it is composed of fibers 200u core diameter each. Half of them (approximately 30) have a very good transmission in the red and near IR (85%) and the other half are optimised in the blue region and visible regions (60% average).
System A
The Calibration Lamps Unit is installed in the IRSPEC Control rack.
System B
This rack contains the following units:
Control Unit
The Control Unit contains all the interfaces to drive the CLS. It is a 4-HE chassis and consists of the control panel (CP) and the control electronics (CE). The CP is made as a door panel; the CE is incorporated in a standard 3-HE chassis.
Control Panel - System A and System B
Control Electronics - System B
Control Electronics - System A
ATTENTION: THE BOARDS MUST BE PLACED IN THE SAME SEQUENCE AS INDICATED TO AVOID SHORT CIRCUITS
Switches and LEDs
The switches and LEDs have the same functions in both Systems A and B, namely switching sources and shutters on or off.

For the black Body (System A):
Manual Lamp Select Board
This board is used to interface the thumb-wheel switches and the 7-segment displays of the control panel to the MCB. In local mode to select a lamp:
The schematic of this board consists of two independent parts:
The thumb-wheel interface is built with IC's 1 to 7, 11 and 12. The first part of the circuit is an encoder; each switch position is converted into a 4-bit hexadecimal value, which is added to a selectable 4-bit value from MUX IC5. This MUX is activated only for positions greater than 10. For positions lower than 10, the value of the B inputs (= 0) are added. The result of this addition appears on the input of the latch IC 6. A store signal clocks the input to the output and to the MCB.
The display interface is straightforward, a 4-bit value (position) from the MCB is converted into 7-segment information IC9 = PROM. This 7-segment data is buffered in ICs 8 and 10. The contents of the PROM are as follows:
| PROM ADDRESS (actual position) | PROM DATA (corresponding 7 segment value) |
| 0 | 3Fh |
| 1 | 06h |
| 2 | 5Bh |
| 3 | 4Fh |

Component List:
Interconnect Board (ICB)
This board is used to interconnect the 12l + 12s and the 4l + 4s interfaces to the Control Panel. The connection between the interfaces and the ICB is via flat cable (for easier maintenence). The switches and LEDs are separately wired to the ICB. Drawing CS-P-1582A shows the printed circuit of the ICB. Drawing CS-E-1582A shows the circuit diagram of the ICB.
Twelve Lamp/ Twelve Sensor Interface (12-ls)
The inputs of this board can be the switches 1-12 on the control panel or the signals from I/O board 5, row A, in the Autoguider rack. The output of the board is the status of the lamps. This status simultaneously changes the LEDs on the frontpanel and the I/Os to the computer.
Refer to the upper left corner of the circuit diagram ( CS-E 1581A):
Select Board
Jumpers 1+4 and 2+3 have to be installed on the CAMAC select board (see Drawing CS-E-1678).
Component List for 12-ls
Four Lamp/ Four Sensor and Remote Interface (4-ls+r)
This part of the circuit is identical to the 12-ls interface; refer to Drawing CS-E-1587A (centre area). IC1, 2, 7 and 11 are for the lamps; IC22 and 23 are for the sensors.
For sphere control, the switch information is serialized and sent to the SCU, in which the information is again available in parallel. The chip-set used here is a simple encoder/decoder set. The transmission frequency can be set with an RC-network. For each set (transmitter-receiver) an address is foreseen, this address can be set:
Transmitter
Information from the switches or I/O board appears simultaneously on the latch (IC12), on the comparator (IC13) and on the transmission chips (IC15 and 16). The comparator compares the new information with the old, and in case of a difference the "=" output becomes active. This output activates the monostable (IC 14) which creates a pulse to latch-in the new information, so the "=" output of the comparator becomes inactive. On the falling edge of the first pulse, a second pulse is generated and activates the transmission enable (TE) input. The parallel information is serialized and sent via a driver (IC17) to the remote interface. The status of the SCU is sent back continuously.
Receiver
The new information from the remote interface is received, via optocouplers IC30 and 31, in the receiver chips (IC29 and 30). The status appears at the outputs and is stored into latch IC24, with the use of the valid transmission output. From there the procedure is the same as for the 12-ls interface.
Note: A test of the board can be done in an easy way. Connect the outputs of IC17 with the opto-couplers IC30, 31. Namely:
When a switch is set, the transmission should take place and be received on the chip-set IC28 and 29.
Component List
Backplanes
These are the backplanes for the two previous boards, CS-P-1586A for the 12-ls and CS-P-1588A for the 4-ls+r interface. These are used to simplify the wiring of the control unit. Both have the same connector types:
Additional 6-solder point are foreseen on the 4-ls+r backplane for the serial link to the SCU. Drawings CS-E-1586A and CS-E-1588A show the circuit diagrams.
Power Amplifier (PA)
Refer to Drawing Number CS-E-1524.
This is a traditional power amplifier, structurally almost the same as the PA used in the NIM units. The speed-reference and the tacho-reference are connected to pin 2 of IC1. The component R6-R7 and C1 are used to adapt the speed and to filter the tacho signal. P1 and R3 not used, the manual switch (to move the wheel) is not implemented. The latter could cause position problems when using this option. When the wheel has to be turned by hand, take out the fuse in the PA. The PID controller is formed by IC's 2 and 3; resistor R9 sets the proportional value, R14, C7 the integral part and R15, C12 the differential part. The latter is not used on this board. The signal from the PID controller is applied to the power stage. Resistors R20 and R20A are the current limiters. Current regulation can be implemented by using R21 (power resistor) and IC4 (this feature is not used in this application). Some parts of the output are very common for PA as there are:
Component List
Motor Control Board (MCB)
Refer to Drawing Number CS-E-1575A.
The main task of this board is to compare a selected 12-bit value (the destination) with a converted 12-bit encoder value (actual position). When the values are different, the board forces the motor to the point of equilibrium. The board contains three cascadable ALU's (IC22-23-24) which are set so that the actual value (input B) is subtracted from the destination value (input A); (C0, S1, S2 and S3 have to be set properly, see data sheet 74LS381). The result of this subtraction is applied to the D/A converter (IC31) which supplies the reference value for the power amplifier.
The destination value is pre-programmed, and is the data output of the Proms IC17-18. The address input of these Proms is a lamp position (from 1 to 11) coming from the thumb wheel switches or from the I/O board. The prom address can also come from the MUX IC7, but this is only in case of start-up, zero or limits. The actual position is the converted encoder position.The encoder phases are received on IC10 and applied to the discriminator IC11; the latter generates the up and down pulses for the counters (IC19, 20 and 21).
The jumpers A, B, AA, BB are to adapt the board to the phase signals from the encoder. Jumpers M2 and M1 give a multiplication factor for the up-down pulses. The counters can be pre-loaded with the value on jumpers B0-B11. The input to and the output from the board are realized in the same way as for boards 12-ls and 4-ls+r, namely via opto couplers.
As mentioned earlier, the LOC/REM condition enters this board, on IC1 and IC31. The latter is an EXOR function which make it possible to switch the system to LOC or REM independently of the position of the switch or the value of the LOC/REM bit in the I/O board. The LOC/REM condition is also applied to the other two boards (12-ls and 4-ls+r). The value for the proms (IC17-18) and the position on the wheel is shown in the System Diagram below (for System B).
Control Sequence.
If A is greater than B---> V is positive-----> Motor turns in positive direction.
If A is less than B---> V is negative-----> Motor turns in negative direction.
At start up:
The motor starts turning in the negative direction until it reaches the zero mark. Once this is detected, the counter is cleared, the destination becomes a certain lamp position, which is latched in the system, and the wheel turns to this position.
Limit switches are not installed, but to complete the description of this sequence these possibilities are also given in the table below.
| CONDITION | ACTUAL POSITION B | DESTINATION A | OUTPUT OF PA |
| Start-up | 000h | FFFh | -V |
| Zero | 000h | XXXh | -V |
| Limit- | FFFh | 000h | +V |
| Limit+ | 000h | FFFh | -V |
The figure below gives the positions of the different lamps and the corresponding addresses.

Backplane - Motor Control and Power Amplifier
There was a need for a dedicated backplane for these two boards, namely:
On the board (Drawing Number CS-E-1578A) 5 connectors are used:
The backplane contains some logic, to interface with:

Local Interconnect Board (LIB)
The LIB is implemented for straightforward cabling between the control unit and the power supplies. It connects the following units:
The board is used for the following functions:
Power Supplies Unit
The drawing below gives the assembly drawing of this unit. All power supplies for the lamps and shutter on the wheel are integrated in this unit. The local interconnect board receives the signals from the control unit and re-distributes these signals to the corresponding solid state relays.
The outputs of the power supplies are collected on the terminal strip in back of the PSU. In total there are three different types of power supplies:
The wiring for PS 1-4 is somewhat special, since the ignition voltage for the lamps is about 1,2 KV.
On the front panel are two milliammeters for the Fe (Hollow-cathode) lamps.
ATTENTION: the manufacturer specifies the normal working current for the two lamps from 0 - 15 mA. Working current normal = 10 mA.
See the drawing below for details of the front and rear panels.
The front panel contains the two milliammeters for the Fe lamps, and two potentiometers to change the current of the lamps.
The rear panel contains all connectors for the PSU:
The numbering of the solid relays does not correspond to the numbering of the power supplies. See table below.
| POWER SUPPLY POS. | SSR POS. | LAMP TYPE |
| Ballast 1 | 5 | HgCdZn |
| Ballast 2 | 6 | He |

Remote Interface
This interface works together with the 4-ls+r interface and has the same structure. For details refer to Subsection 6.2.1 and to Drawing Number CS-E-1589A.
Component List
Lamp Shutter Interface
Refer to Drawing Number CS-E-1673. This board is controlled from the remote interface. The lamp-shutter interface gives the possibility to drive, in total, four lamps and four shutters.
The interface for lamp control is, as in the power supplies unit, namely with the use of solid state relays.
The shutter interface is somewhat different from the one used on the wheel. A DC/DC converter supplies the 30V, to load the capacitors C1-C4, via limiting resistors R1-R4. The max current of the DC/DC is 170mA hence the resistors R1-R4 are relatively high. The shutter opens when the capacitor is discharged over the coil of the shutter. Once the shutter is open, it is held via the diode D9 (D10-D12 for the other shutters). The shutter closes by removing the ground connection through U2,4,6,8.
Component List
Sphere Control Chassis
This chassis is a KM7 which contains the following parts:
An overview of the rear panel is shown below.
A special cable is used to wire-up the ballast type power supplies, since a relatively high ignition voltage is used. Also the connectors on the back panel are high voltage resistive. Concerning the current supply for the Th lamp, the milliammeter is mounted in the back of the unit and can be reached when opening the back panel.
Pay attention to the current supplied to the lamp. Specified from 0-15mA, it should be set to approximately 10mA.
The Wiring Diagram of the SCU is shown below.
The system can be driven from the I/O board or from the front panel depending on the local/remote status.
In the remote status, information between computer and calibration system is exchanged via the six registers to/from the I/O board. These six registers are divided into:
The following possibilities are used:
| BIT 7 | BIT 6 | DESCRIPTION |
| 0 | 0 | System in idle position, no information exchange |
| 0 | 1 | The contents of the WR registers are reflected in the RR registers. The contents of WR2, WR3 and bits 0 and 1 are sent to the slave unit |
| 1 | 0 | Command to ask for the actual status of the lamps, shutters and Black Body. Data received is stored in the RR and the LR registers |
| 1 | 1 | The contents of the WR registers are reflected in the RR registers. This command can be used to test the cable between calibration system and I/O board |
In the local status the actual status of the switches (output of registers SR1, SR2 and SR3) is compared with the previous stored status. The actual status is stored in the buffers and will be sent to the slave unit when there is a difference from the previous status. The master waits a certain time after the new status is sent, to ask for the actual position of the lamps and shutters. The received new statuses are stored in registers LA1, LA2 and LA3. A lock indication from the Black Body is not yet implemented.
Hardware
The PCB boards used in the master unit are shown in drawing numbers CS-E-1726 and CS-E-1727.
Drawing number CS-E-1728 shows the circuit diagram of the master control board. The microprocessor module is plugged on the board in a piggy-back configuration. In CS-E-1728, connector rows A, B and C in the lower left corner are foreseen for the micro module. This module leave the address space $8000 to $8FFF for the user, the line 'user' (pin A16) is enabled in this address range. The module has also an RS232 interface incorporated, and brought out via connector 2. This connector is on board and is not reachable on the front panel.
The address selections are made with the proms, U1, U2 and U6. The serial communication to/from the slave is implemented with an asynchronous communication interface adapter U23 (68HC51) and an RS232 interface U24 (MAX233). The latter has the advantage of having transmitter and receiver in one chip and that no external +12v/-12v supply is needed. The board is galvanically insulated from the I/O board and from the slave unit.
The I/O board is connected with the master board via the following Opto-couplers:
The procedure to latch information in one of the registers U15, 14 and 10 is as follows:
To go to the next latch, first disable the CE signal (set high) before changing address and/or R/W lines. This procedure has to be followed to be sure that address and R/W are stable before the chip is enabled. The same procedure should be used when reading information from the master board, via port PA3.
The frontpanel interface (CS-E-1727) is connected to the master board via connector 1. The switch and LED register have a specified address in the user address range. This register is continuously read and updated when working under local. CS-E-1726 gives the circuit diagram of the backplane.
Software
No additional explanation is given about the software, since the final version will differ from the one presently installed.
The only function of this unit is to receive and compute information coming from the master unit. A test of all lamps, shutters, the Black Body and the read back registers is done during start up. The result of these tests is displayed on a terminal, if one is connected. The future update of the software shall include a stand-alone mode in which the different tests can be done from a terminal on the master unit.
Slave Control Board
This board has the same structure as the master unit. Namely the microprocessor module, communication chip set, some latches for I/O and a D/A convertor. The addressing has been done in the same way as for the master. The circuit diagram is shown in Drawing number CS-E-1729.
Received information is put in:
