Status LED
QS820 Ringers have a single tri-color LED. The LED indications are listed below.
LEDs:
*
= On
Green Amber Red Condition
* Lamp Test
*
Internal Fault
• Thermal shutdown
• Ringer Failure
*
External Fault
• Ring Return not terminated
• Output limited – excessive output load
• Output limited – excessive temperature
Flashing
Communication Loss
Flashing
Standby
* Normal Operation
none
• Input Under / Over Voltage
• Ringer Not Fully Inserted
1. Conditions are listed in precedence order, highest precedence on top, i.e. when both Internal
Fault and External Fault conditions are active, the LED displays the Internal Fault pattern.
2. Normal is only active when no other condition is active.
3. Fan Fail (chassis fan) is not a Ringer failure and does not affect LEDs.
4. Output Power or Voltage is reduced (limited) to less than the Operational Setting due to
excessive external load or excessive ringer temperature.
Status Descriptions
Normal Operation: Ringer is operating within specification, without output limiting.
Standby: Ringer is capable of Normal Operation, but its output is disabled due to one of two
conditions:
• Redundant Standby: This is the Spare Ringer and the Primary is operating normally
• Remote Standby: The Controller has placed the Ringer into Standby
Communications Loss: Ringer has lost communications with the Controller. Ringer
operation continues at the last received configuration.
External Fault: Ringer output is limited in response to an external condition.
• Ring Return Not Terminated: Ringer output is disabled. Ringer Chassis Jumper J12
is in the EXTERNAL position and there is no external connection between Ring Return
and either Battery or Ground. Recovery is automatic when connection is made.
• Excessive Temperature Reduced Output: Ringer output is reduced due to high
Ringer component temperature. Recovery is automatic when component temperatures
return to safe values.
