PMCU in the Series 8000 ACS
Power
The PMCU device operates at 48VDC~52VDC delivered over its
Ethernet connection to the drive cabinet.
Dependency
An ACU is required in order to display signal strength. If no ACU is
detected, the signal display shows: -ACU
PMCU buttons except Halt or Local will be ignored if the ACS is in
standby, manual, or tracking mode, or if there is no ACU and the drive
cabinet is in remote mode.
Drive Cabinet (DC) and PMCU cooperate
DC and PMCU are always in the same Local or Remote mode.
When under Local control, the DC and connected PMCU are both
active and can move the antenna. The last button pressed on either
takes precedence.
The PMCU and DC display the same motion.
Except:
The PMCU’s toggle and slew buttons do not affect the DC’s jog panel.
An LED indicates when each mode is active on the PMCU.
Unplugging
If the PMCU is
unplugged
after it was in local mode,
the DC goes into re-
mote mode and the ACU is in standby.
Testing
Test mode 1:

buttons) while powering up. It sequences through all the LEDs
–
