Systems Customer Service.
Alternate Function for K5
An alternate K5 function may be selected by installing a jumper onto JP2 on the
control card. The STANDBY-READY function is asserted (K5 closed) when the
power supply completes the transition from the STANDBY-WAIT (flashing yellow)
to the STANDBY-READY state (steady yellow). K5 remains closed for the LAMP
ON state (flashing or steady green), the QRO state (alternate flashing of yellow and
green), and the return to the STANDBY-READY state (steady yellow). K5 opens
during the OFF/RESET state and the STANDBY-WAIT state (flashing yellow) from
either the LAMP ON state or from the OFF/RESET state.
LAMP ON (K4) 9, 10 Closed 1 A @120 VAC
(10mA minimum)
K4 contacts close when photocell
is satisfied. Note: If using K4 for
press control, wait 6-8 seconds
for lamp output to stabilize.
PRESS ENABLE
(K5)
11, 12 Closed 1 A @120 VAC
(10mA minimum)
K5 contacts remain closed when
no unit or system error exists.
