Power – BAQ-UP™ (QRED) Redundancy Switch with Backup Amplifier – Installation & Operation Manual
CHAPTER 1: DESCRIPTION OF INTERFACES
Alarms:
Alarm 1 (form C) for the primary amp
Alarm 2 (form C) for the secondary amp
Switch:
Remote control switch contacts
Description:
The form C contacts may be used to switch any warning device that can provide a notification in case either
amplifier has failed. The remote switch contacts may be used to force a switch from the primary to the secondary amplifier.
b)
Front:
(with cover removed):
Green LED: — 5V power on
Yellow LED (warning):
• On: using reference levels stored in EEPROM
• Flashing (1/sec): Needs to set reference levels
•
Flashing (3/sec): Switched to the secondary amplifier by the remote control switch
Red LED (alarm):
• On: Primary amp failure
• Flashing (1/sec): Secondary amp failure
• Flashing (3/sec): Input signal low/primary amp and secondary amp failure
RF Detectors:
• Primary Amp RF Level Detector: DC level proportional to the primary amp RF output level
• Secondary Amp RF Level Detector: DC level proportional to the secondary amp RF output level
Test Points:
• Primary Amp DC Level
• Secondary Amp DC Level
Switches:
• Controller Reset: Restarts the microcontroller program
• Set Ref Levels: Stores the levels as references and start monitoring the amps
