Signal Description
Power Connector
P1) V~ Hot: Supply to board approximately 125V~.
P2)
V~ Common: Common to board is the common also for relays, shutter fans,
and the internal lamp head interlock. (This may not be at ground potential
and should be measured with caution).
P3) Lamp Fans: V~ proportional drive output for the blowers in the lamp head.
P4) Shutter: V~ output to drive the shutter motor.
P5)
High: V~ Output to drive the high relay, which engages the high power
capacitor bank during warm-up and high power exposures.
P6)
Medium: V~ Output to drive the medium relay which engages the medium
capacitor bank during warm-up and both high and medium level exposures.
P7) Unit Fan: V~ Output to drive the power supply blower or fans.
P8)
Power Relay: V~ Output to drive the main relay. This provides power to the
lamp circuit.
P9) Not currently used.
P10)
Aux: Terminal connects to the signal connector for accessories (Not used in
most equipment).
P11)
DC Common: Circuit common for low voltage signals from the lamp (this
may not be the same potential as V~ Common connection and should never
be interchanged).
P12)
Position: Shutter switch active signal from the lamp head - Low voltage
when the shutter is open and 12VDC when closed.
Switch Connection
S1) V~ Hot: Output, V~ supply for internal accessories.
S2) V~ Common: Output, V~ common for internal Accessories.
S3) Not currently used.
S4)
Aux: Terminal connects to the power connector for accessories (Not used in
most equipment).
S5)
DC common: DC circuit common for switches (Not the same as V~
Common).
S6)
Power Switch: Switch to turn on power. Low (0V) for power on. The power
can also be turned on by the integrator through the outlet. (Only a signal !
Power is always present on the PC Board).
