3.2.5 REMOTE FAIL-SAFE X-RAY
ON CIRCUITS:
The DF3 series provides a 24VDC circuit for a
remote X-RAY ON lamp . This circuit provides
fail-safe sensing of the lamp. (The front panel X-
Ray on lamps are also fail-safe sensed). Optional
12VDC and 220VAC lamps can be
accommodated. See Figure 3.6A and 3.6B for
remote fail-safe connections.
3.2.6 REMOTE WATER SOLENOID
CONTROL SIGNAL:
Remote signals are provided for tube water flow
control and other uses. +24V and 220VAC
signals are provided. These signals are switched
ON when X-RAY ON is switched on. These
signals can also be controlled (independently)
when the power supply is switched ON. This is
accomplished on the rear panel INTERFACE
PWB. JP2 controls the 24V signal and JP3
controls the 220V signal. See Figure 3.7 for
remote water flow connections. External
interlock connections can also be used for water
flow interlock as shown in Figure 3.7.
