• RELAY PULSE OUTPUT
Relay K1 can also be used as a dry switch closure pulse
output to operate devices such as remote counters or batch
control panels (output frequency not to exceed 5 HZ.) To do
this, move wire from terminal #8 to terminal #7.
See how to program pulse output duration on page 13.
• BATCH COUNTER OUTPUT
Relay K1 can also be used to provide a switch closure at
the end of each batch to a remote batch counter or other
device. To do this, move wire from terminal #8 to terminal #7.
See how to program cycle output on page 10. The transistor
output on terminal #7 can be programmed for one of three
functions:
1) To provide a scaled pulse output.
2) To provide a pulse at the end of each batch.
3) To provide a signal whenever the hi or low flow rate
setpoints have been exceeded.
See function #33 for detail programming mode and tech-
nical brief for transistor output specifications.

Scaled Pulse Output:
Generally used to drive an elec-
tronic remote counter or totalizer, or to interface with
remote controllers. When using output in this manner you
can select a pulse duration of 1 ms to 99 ms depending on the
output frequency and the sensitivity of the receiving device.
End of Batch Signal:
Can be used to totalize batches or
cycle runs during a period of time, or to cascade several
PC100s, so that one PC100 can start when the other finishes.
This signal duration is adjustable.
• FLOW ALARMS
Used with a low powered piezoelectric or similar sounding
device. It is energized when either the hi or the low flow
setpoints have been exceeded and can be programmed to
remain active until the end of the batch or to reset if the flow
returns within preset limits.
Note: Transistor outputs #1 and #1A are de-energized the
same as Relay K1, and transistor outputs #2 and #2A, the
same as Relay K2. Therefore, these outputs can be used to
drive external relays or other devices simultaneously with
the batch and prewarn relay outputs.
• START, STOP AND RESUME
These operations can be wired remotely for fast emer-
gency override, or for cascading several units. If you inhibit
these functions with function #41, only STOP and RESUME
will still be operational with the remote control, START will
not. If a sustained ground (DC common) is applied to the
remote stop, all inputs are inhibited.
• The RESET CYCLE and RESET TOTALIZER are useful
for end of shift coordination and control. Both inven-
tory totalizer and cycle counter can be reset to zero.
• The PRINT input allows you to request printed infor-
mation at any point during the operation, in order to
inspect batch, flow, and inventory parameters.
