• Excessive Temperature Reduced Output: Ringer output is reduced due to high Ringer component temperature.
Recovery is automatic when component temperatures return to safe values.
Excessive Output Load: Ringer output load exceeds 100VA.
Reduced Output: Ringer provides limited ringing output at 100VA by reducing Vac as low as 50% of Vac set point.
Hiccup: If Ringer output is overloaded to Vac less than approximately 50% of the Vac set point, the Ringer enters
the hiccup mode.
Recovery is automatic when the external fault is removed.
In this mode, the Ringer shuts-down and restarts briefly at intervals of approximately 2 minutes to test for the
presence of the external fault.
Restart will cause restart immediately.
Internal Fault: Ringer output is disabled (shutdown) due to excessive temperature or Ringer failure.
•
Recovery from Internal Fault
Excessive Temperature recovery is automatic when the temperature returns to a safe value.
Ringer Failure recovery is manual, requiring one of the following:
• Removal of dc input power (remove and re-install Ringer in Ringer Chassis)
• Restart command from Controller (from front panel menu or remote)
• Ringer Failure is usually permanent and will reoccur upon completion or the recovery attempt.
