Signal name 

Description

1 

+12 V 

+12V dc output (100mA max.)

2 

Lamp change signal 

This signal is output when the accumulated lamp operation time reaches 4000 hours 
(L8253:3000 hours).

3 

Lamp ON signal 

This signal is output when the lamp ON.

4 

Lamp STABLE signal 

This signal is output about 5 minutes after the lamp ON.

5 

Shutter OPEN signal 

This signal is output while the shutter open.

6 

Output intensity upper limit signal 

This signal is output when the output intensity reaches the upper limit.

7 

Alarm signal 

This signal is output when an alarm indicating overheat, lamp error, shutter error or 
lamp change is activated.

8 

Output intensity lower limit signal 

This signal is output when the output intensity reaches the lower limit.

9 

Output intensity UP 

When this signal is inputted while the shutter is open using the manual mode, the 
output intensity increases (the diaphragm opens) as long as it is inputted.

10 

Lamp OFF trigger 

Momentary (about 0.5 sec.) input of this signal makes the lamp turn off.

11 

Lamp ON trigger 

Momentary (about 0.5 sec.) input of this signal makes the lamp turn on.

12 

Shutter auto trigger 

Momentary (about 0.5 sec.) input of this signal makes the shutter operate in the same 
way as when the shutter button in auto mode is pressed once. (The shutter opens/
closes as set in the program.)

13 

Shutter OPEN / CLOSE 

When this signal is inputted, the shutter opens as long as it is inputted. When no signal 
is inputted, the shutter closes.

14 

Output intensity DOWN 

When this signal is inputted while the shutter is open using the manual mode, the 
output intensity reduces as long as it is inputted. (The diaphragm closes.)

15 

GND 

COM of signal output/signal input

●

  To use the external control function, use the plug for the ex-

ternal control signal supplied with the main unit.

Insert  the  plug  into  the  signal  I/O  connector  on  the  back  of  the 
main unit, and secure it with the left and right screws. 

■

  Signal Output

The circuit between the signal output pin and the GND pin 
(see  the  above  table)  turns  ON  to  output  signals  indicating 
each condition. The load connected to the output must meet 
the following conditions.

  • Voltage: Maximum 50 V
  • Current: Maximum 30 mA

■

  Signal Input

Each operation is possible by turning ON the circuit between 
the signal input pin and the GND pin (see the above table).
The contact or transistor used to implement the short must 
be rated as follows.

  • Withstand voltage: 30 V minimum
  • Current: 50 mA minimum

●

  Although a protective resistance (100 

Ω

) is included 

in the output transistor, also put a current limit resis-
tance (1 k

Ω

 min.) in the external circuit so as to pre-

vent a current exceeding the rated level from flowing.

cated “trigger”, momentary (about 0.5 sec.) ON is provided.
