Counter Mode
10.5 Input Pulse Test
A. Set the mode switches as follows:
1. Position 1 and 3 on, 2 and 4 off.
B. Set the count switches to 00 to enter the
diagnostic mode. This mode enables the user
to determine if the proper input pulses are
being received at the count input (ter. #3).
1. Dry Contact Input: mode switch 4 should
be in the off position. Depress the test switch
and hold. A red LED should illuminate. When
the dry contact input is received at the counter
input (ter. #3) the green LED will turn on and off
and the red LED will illuminate again. This will
normally occur very quickly and give the
appearance that the green LED blinks on when
the pulse input is received and removed.
2. Voltage Pulse Input: move mode switch 4
to the on position. Depress the test switch and
hold. A green LED should illuminate. When the
voltage pulse input is received at the count input
(ter. #3) the red LED will turn on and off and the
green LED will illuminate again. This will nor-
mally occur very quickly and give the
appearance that the red LED blinks on when
the pulse input is received and removed.
