LVD Board)
No Ringers installed in
a Ringer Chassis.
Ringers not fully
seated in Ringer
Chassis.
Single Rectifier not
receiving ac power.
•
AC input circuit
breaker has opened.
•
AC input voltage is
out of range.
Rectifier output has
dropped below 36V,
rectifier has entered
hiccup mode.
Possible Solution(s)
1. Verify that there is no
obstruction of the vertical
air flow path.
2. Reset rectifies by removing
them, waiting
approximately 30s and
replacing them.
3. If problem persists, replace
the rectifiers.
4. If problem still persists, call
your local field
representative.
1. Reset the rectifier(s) by
removing the rectifier(s),
waiting approximately 30s
and replacing the rectifier
(s).
2. If problem persists, replace
the rectifier.
3. If problem still persists, call
your local field
representative.
1. Replace Distribution
Module Board. (Note 2)
2. If problem persists, call
your local field
representative.
1. Fully seat Ringers in Ringer
Chassis.
2. Install Ringers in Ringer
Chassis.
3. If problem persists, call
your local field
representative.
1. Verify ac power to rectifier
is available.
2. Verify rectifier input circuit
breaker is closed.
3. If problem not corrected,
replace rectifier.
Replace rectifier.
