INT (Remote Interlock) Indicator – illuminates green to indicate that a remote interlock circuit is
closed and that lasing may be enabled. The INT indicator is red and lasing is disabled if the interlock
input is open.
3
TMP (Temperature) Indicator – illuminates green to indicate that laser temperature is within limits
and that lasing may be enabled. The TMP indicator is red and lasing is disabled if the laser’s tem-
perature rises above safe operating limits.

second delay, lasing will begin when a PWM Command signal is applied.
5
SHT (Shutter) Indicator – illuminates blue to indicate that the shutter is Open and that lasing may
be enabled. The SHT indicator is o and lasing is disabled if the shutter is Closed. When the shutter
is switched Open, there is a ve-second delay until PWM inputs are recognized.
