24 vac sequencing voltage is supplied by the using
system when the system
+6
vdc and -3 vdc are at
operating levels. This sequencing voltage picks Kl
sequencing contactor and
K2
sequencing contactor
and K2 sequencing relay in the 1132 Printer if the
1132 motor switch is on. The sequence of bringing
up all voltages is under control of the using system
power sequencing.
5. 4. 2 Power Down
Power down sequence is controlled by the using
system power sequencing; however, the 1132 Printer
sequencing relays can be dropped by turning off the
1132 motor switch. Dropping the sequence relays
does the following:
1.
Stops the 1132 main drive motor.
2.
Stops the use meter.
3.
Drops the +48 vdc.
4.
Drops the 20 vac.
NOTE: Logic voltages are controlled by the
CPU, and they are present in the 1132 with the
motor switch off.
