Synchronizing a Model JR-2
Suppose there are five JR-
2’s in the field and one is
accidentally turned off and needs to be restarted and
resynchronized. All the units could be brought back to a
single location, daisy chained together, and started as in
example 2. This procedure will work, but is rather inefficient.
Therefore, the JR-
2’s are constructed so that any one of the
operating units may be used as a master to restart the failed
slave unit. Simply take the slave unit to the working master
location and follow the procedure below. The JR-
2’s
automatically output a trigger pulse to the SYNC receptacle
once a minute when running.
Procedure:
1. Turn the slave unit to be resynched OFF,
and then ON.
2. Check or set the functions on the slave to the same
as those on the master. Press the function key on
both the master and the slave to display their
settings.
a. START SET;
b. ON CYCLE;
c. OFF CYCLE;
d. STOP SET;
e. START RELAY SWITCH CLOSED.
3. Press "CLOCK SET' on the slave and enter a time
which is a minute or two ahead of the MASTER.
