7. Troubleshooting
Refer to this section if the 232e keypad is not operating correctly as
described in this manual.
Problem
Solution
The LEDs are slowly
cycling from right to
left and backlighting is
off.
The 232e keypad is designed to monitor the
input voltage and this is an indication of
under-voltage. The under-voltage threshold is set
to 8.5VDC, and when the voltage drops below
this limit, the low voltage warning starts and
backlighting is turned off. To solve, raise the
voltage to between 12-24V.
The LEDs are rapidly
cycling from left to
right and the keypad
has lost all operation.
The 232e keypad is designed to monitor the
input voltage, and this is an indication of
over-voltage. The over- voltage threshold is set to
36VDC, and when the voltage rises above this
limit, the over-voltage warning starts and the
keypad loses all operation. To solve, lower the
voltage to between 12-24V.
The master code does
not work.
Perform the programming mode loopback and
reset the master code using the programming
command.
No LEDs are lit on the
keypad
Power is not reaching the keypad. Using a
voltmeter, confirm that there is voltage at the
keypad on the red and black wires. If there is no
voltage at the keypad, verify that there is voltage
at the power supply. If there is no voltage at the
power supply, call the manufacturer of the power
supply. If there is voltage at the power supply
but not at the keypad, verify there is no break in
the wires, then check continuity in the whole
length of the wire run. To verify that the keypad
is working, you can power the keypad with a
12-Volt Battery.
If the 232e Keypad still does not work after troubleshooting, please
call IEI’s technical support department at 1-800-343-9502 (outside
MA) or 1-800-733-9502 (inside MA). Operating hours are Monday
through Friday from 8:00 A.M. to 7:00 P.M. Eastern Standard Time.
