GV30N TROUBLESHOOTING MANUAL RESPONDING TO ALARMS
VERSION 0.1 2014-11-01 PAGE 4.1.25
Module #: PS A (or B)
AC Fail Power Supply (red) This alarm occurs if one of the two module power supplies (1 or 2) is
reporting an ac failure, indicating its ac input voltage is less than 175 V ac.
If a bank of power supply modules are indicating an AC Fail alarm, it is
possible that an ac phase loss has occurred. Check the ac voltage applied to
the suspect power supply module. If the ac voltage is acceptable, replace
the module (see
“Power Supply Module Replacement” on
page 4.1.49
).
Module #: PS A (or B)
Current Limit Power Supply (red) This alarm occurs if one of the two module power supplies (1 or 2) is
reporting a current limit, indicating that the power being delivered by the
module has reached 2750 W. This may relate to the operating mode and/or
the load impedance at the transmitter’s RF output. Check for other
transmitter related alarms.
Module #: PS A (or B)
Fail Power Supply (red) This alarm occurs if one of the two module power supplies (1 or 2) is
reporting a PS failure, indicating its output voltage is outside its acceptable
range, based on the control setting. Check the dc voltage output of the
suspect power supply module. If the dc voltage is out of tolerance, replace
the power supply module (see
“Power Supply Module Replacement”
on page 4.1.49
). If the voltage is acceptable, suspect the PS interface
PWB (A1).
Module #: PS A (or B)
High Temperature [PS
A (or B) Temp] Power Supply (red) This alarm occurs if one of the two module power supplies (1 or 2) is
reporting a high temperature alarm, indicating its operating temperature
has exceeded its internal threshold of 105°C (221°F). Both module power
supplies are inhibited while this fault exists. This alarm is most likely caused
by a module fan failure or blockage. Verify the module turns on and its fan
is operational. If the fan is not operational, inspect it for possible blockage.
If necessary, replace the power supply module (see
“Power Supply
Module Replacement” on page 4.1.49
). If the alarm persist after
replacing the module, suspect the PS interface PWB (A1).
Module #: PS A (or B)
Low Line Power Supply (red) This alarm occurs if one of the two module power supplies (1 or 2) is
reporting a low ac input voltage (less than 175 V ac, higher than 90 V ac).
The power supply will limit its associated module’s output.
Module #: PS A (or B)
Missing Power Supply (red) This alarm occurs if the module power supply (A or B) is removed, or has not
been detected on the serial bus. Install an operational power supply
module. The alarm may persist for several seconds after replacing a power
supply module, before the power supply module is recognized. If the alarm
persists after one minute, try reseating the power supply module. This alarm
may also be caused by an ac power loss to the power supply module.
