Troubleshooting
The clock is not running. What do I do?
a) Measure the input voltage to the clock. The voltage should measure 85-135 volts in the 110 volt model or 10-28 volts in the 2.5”/24 volt
model and 16-28 volt in the 4.0”/24 volt model.
b) Make sure the transformer is an isolated transformer if using a 24 volt model.
c) Make sure the ground wire is not touching other wires.
NOTE: If you fail to follow instructions a and b listed above, the fuses can be blown.
The clock is not receiving an input signal. What do I do?
a) Make sure that the RS485 is connected properly when using in RS485 slave mode.
b) Make sure that the polarity of the communication wire is correct when using the clock in 2 wire digital communication slave mode.
c) If using 2 wire digital communication, make sure the clocks are the 24 volt model.
There is data noise bleeding into the intercom line. What do I do?
Reduce the transmission rate from the master clock to once a minute.
