Section 6: Trouble Shooting.
Refer to this section if the 212iL is not responding correctly to the operation outlined in this instruction
manual. The 212iL has been designed to operate with 12-24 VDC only. Verify that the voltage
powering this keypad is within these parameters.
Situation 1:
LED's are slowly cycling from right to left and the Backlighting is off.
Reason:
The 212iL has been designed to monitor for low voltage. Once the low voltage
has been detected, the keypad shuts down some of its options like backlighting
to ensure operation of the keypad until the problem can be attended to.
Solution:
Check the output voltage of the power supply with a meter to verify the output
voltage rating listed for that device. If it is below the voltage threshold of 9 VDC,
you must increase the voltage beyond the minimum rating of 9 VDC.
Situation 2:
LED's are rapidly cycling from left to right and the keypad has lost all
operation.
Reason:
The 212iL has been designed to monitor for over voltage. This is a very "severe"
condition and therefore significantly affects the keypad’s operation. Once the
over voltage has been detected, the keypad shuts down all operation and will not
operate until the voltage irregularity has been corrected.
Solution:
Check the output voltage of the power supply with a meter to verify the output
voltage rating listed for that device. If it is over the voltage threshold of 30 VDC,
you must reduce the output below the threshold.
Situation 3:
The Master code is not allowing access to the programming mode.
Reason:
There are a few reasons that this situation could occur. The most common is
that the Master code was programmed incorrectly. That is to say that someone
used the incorrect user number to add a user code. The Master code is always
kept in memory with user number "1".
The other reason this could happen is that the code was simply forgotten.
Solution:
Power down the keypad, connect the white/black wire to the Red wire on the
212iL wire harness and power back up. The yellow LED will be flashing
indicating that the keypad is now in programming mode. Change the Master
code by press 1 # (New Master Code) * (Repeat Master Code) * *. When
finished with programming, power down the unit, separate the white/black wire
from the Red wire on the 212iL harness and power back up. The keypad is now
ready to use.
Situation 4:
No LED's are lit on the keypad
Reason:
Power is not reaching the keypad.
Solution:
With a meter check the voltage connection at the 212iL keypad on the Red &
Black wires. Confirm that there is actually voltage at the keypad. If there is no
voltage reading at the keypad, use the meter on the power supply to verify that
voltage is leaving the power supply. If there is no voltage coming out of the
power supply, call the manufacturer of that power supply. If there is voltage at
the power supply, but not at the keypad, use the meter to test each of the wires
for a break in the wire.
