Problem Identification Procedures

10 dBm & 0 dBm no adjustment is needed. If it is not, adjust the “Downconverter
Gain”, then view the RMS value until it is within the –10 dBm to 0 dBm range.
This completes the set up and adjustment of the transmitter using the Axciter
Modulator.
If a problem occurred during set up, contact Axcera field service at 1-724-873-8100.
3.7: Problem Identification
3.7.1: Pump Rack Cabinet Assembly
The Programmable Logic Controller, PLC, makes decisions based on inputs from the
transmitter and the various sensors throughout the pump rank and outside heat
exchanger. To turn the pumps ON the PLC is expecting a high signal from the
transmitter controller. Pump 1 will turn ON, after a 20 second delay pump 2 will turn
ON. Pump 3 will only turn ON if there is a fault in either pump 1 or 2. If 2 pumps
fault the PLC will send an alarm signal to the transmitter controller. The PLC also
controls the heat exchanger fan by monitoring the coolant return temperature from
the transmitter, optional load and optional filter. When the Coolant reaches 50°C the
PLC energizes the fan motor contactor. The PLC issues a warning signal or alarm to
the transmitter system controller when one of the following conditions occurs (See
Warnings/Alarms Table). The transmitter WILL NOT shut down when issued a
warning. The transmitter WILL shut down when an alarm is issued.
