WARNING: Disconnect primary power prior to servicing.
Troubleshooting
6.9.15 IPA_TW, IPA Temperature Warning
If the temperature of an IPA exceeds 85°C the fan will be switched to high speed
and IPA_TW will be registered in the Fault Log. There is a 10°C hysterisis so the
fan will not switch back to low speed until the IPA reaches 75°C or less.
6.9.16 IPA_OT, Fault
If the IPA amplifier temperature exceeds 100°C, as detected by the thermal sensor
on the amplifier, the transmitter will initiate a 3 strike routine. If the IPA in question
is still faulted, the transmitter will automatically switch over to the second IPA. If
one of the thermistors or its wiring is shorted the temperature indication will be
approximately 155°C or higher.
6.9.17 IPA_#_OUT, Fault
This fault indicates that the IPA_1 or IPA_2 is not physically plugged into the
connector. Each amplifier has 2 edge connections which are slightly shorter than the
others. These are used for interlocking. If the amplifier is not inserted far enough
into the connector, these 2 pins will not make contact and the amplifier will not be
activated. The control system will switch to the other IPA if it is not faulted also.
6.9.18 IPA_LOAD, Fault
To check for bad RF Cables, the Master Controller checks Z-Plane currents for
proper IPA load balance. If an imbalance is found, the transmitter is muted.
6.9.19 PSC#_COMM, Fault
This is a communications fault between the PS Controller and the Master
Controller. No action is taken when this fault is detected since the PS Controller is
designed to operate without the Master Controller. It is simply used to alert the
operator to the fault condition. All meter readings in the Diagnostics Display for
the power supply under its control will have an asterisk (*).
6.9.20 PAC#_COMM, Fault
This is a communications fault between the PA Controller and the Master
Controller. No action is taken when this fault is detected since the PA Controller is
designed to operate without the Master Controller. It is simply used to alert the
operator to the fault condition. All meter readings in the Diagnostics Display for
the PAs under its control will have an asterisk (*).
