RC4000 ACU Boardset Chapter 4 Support

4.2.6.8 DRIVE OVERTEMP

When the Power / Drive Board receives a motor over-temp error signal, it will pass the error signal to the
Computing Board. This error will only be applicable to those antennas which have motors that include an
over-temp sense that is fed back into the ACU.

4.2.6.9 DRIVE ERROR

When the Power / Drive Board receives a drive error from an external source, it will pass the error signal
to the Computing Board. This error will only be applicable to those antennas which have motors that
include drive error feedback that is routed into the ACU.

4.2.6.10 EMERGENCY STOP

If the RC4000 is interfaced with an emergency stop switch, it will display this alarm code when the
emergency stop switch has been depressed. The alarm will continue to display until the switch has be
deactivated. During the time when this alarm is active, the RC4000 will not allow any movement of the
antenna.

4.2.6.11 REPLACE HAND CRANKS

If the antenna has hand cranks that have sensed feedback to the RC4000, this error code will display if
the hand cranks are not in a position that allows safe antenna movement via the ACU.

4.2.6.12 ELEVATION INTERLOCK

If the antenna has an elevation interlock switch that has feedback to the RC4000, this error code will
display if the interlock is not in a position that allows safe antenna movement via the ACU.

4.2.6.13 MOVEMENT INTERLOCK

If the antenna has a movement interlock switch that has feedback to the RC4000, this error code will
display if the interlock is not in a position that allows safe antenna movement via the ACU.

4.2.6.14 LOCAL JOG CONTROLLER CONNECTED

If a local jog controller (2.2.7) is connected to the RC4000, the alarm code "LOCAL JOG CONTROLLER
CONNECTED" is displayed. The RC4000 will not allow any type of axis move via remote (serial or
Ethernet) while the jog controller is connected.
