Z-65 Counter Mode
If the Z-65 controller is to be operated in the counter
mode, an input pulse from some other flow monitoring
device must be received by the Z-65. These pulses are
then totalized, and the low powered solenoid is ener-
gized when a sample is needed.
Z-65 Counter Mode
Troubleshooting Steps
1.
Set
the mode switches as follows, refer to,
figure 31:
Position 1 and 3 on, 2 and 4 off.
2.
Set
the count switches to 00 to enter the
diagnostic mode, refer to figure 32. This mode
enables the user to determine if the proper
input pulses are being received at the count
input (ter. #3).
A. Dry Contact Input:
mode switch 4
should be in the off position, refer to
figure 34.
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, figure 33.
