External Control Signals (15-pin D-sub type)
Pin No. 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.

A signal is inputted with the signal input pin and GND turned on (shorted). When indi-
cated “trigger”, momentary (about 0.5 sec.) ON is provided.
