2.0HOW TO OPERATE THE MODEL PC and MODEL PB
2.1What Was The MODEL PC and PB Designed To Do?
In addition to the features of the MODEL RT, the model PC includes a single SPDT relay which can be used to
switch an external component such as a pump, valve, alarm buzzer, etc., on and off in order to assist in the
control of a process. The relay setpoints must be assigned to either the rate mode, the batch (total) mode, or
turned off. The MODEL PC cannot be battery operated.
The MODEL PB offers all of the features of the MODEL PC but includes a contact closure switch instead of a
relay and may be battery operated.
!
High level flow rate alarm.
!
Low level flow rate alarm.
!
High and low level flow “range” alarm.
!
Manual start or automatically timed start batch processing.
!
Proportional chemical feed injector pump control.
2.2What Features Are Available?
!
All controls are front panel programmable.
!
MODEL PC Max. switching load 8 Amp at - 115 VAC, 230 VAC, 220 VAC; 7 Amp at 30 VDC (resistive load).
!
MODEL PB Max. switching load 100 milliamp at 30 VDC.
!
NO / NC contact.
!
Rate alarms can be latched requiring a manual reset.
!
Programmable “alarm release value” provides hysteresis to prevent relay flickering (see page 28).
!
High and low range alarms can be independently programmed.
!
Alarm delay timer temporarily silences alarms for a programmed time from 0-999 seconds.
!
Independent display and resetting of batch count and batch amount.
!
Front panel clearing of batch counts and amounts can be disabled.
!
Turn on / off external devices, for a programmable time from 0-999 seconds per batch.

2.3How Do I Program The MODEL PC & PB?
The Model PC & PB setpoints must be assigned to either the rate mode (option 1), the batch (total) mode
(option 2), or turned off (option 3).
Option 1 - Assign the setpoints to the RATE mode for applications involving the switching of external devices,
such as alarms or valves, when the rate of flow is greater than or less than the programmed flow
RATE value. The Model PC and PB is used to monitor flow RATE in this mode. Example: High or
low flow rate alarms.
Option 2 - Assign the setpoints to the BATCH mode for applications involving the switching of external devices
such as chemical metering pumps, centrifical pumps, solenoid valves, etc., when the amount of flow
is greater than or less than the programmed batch amount value. In this mode, the Model PC is used
to monitor flow total. Example: Manual batch processing or proportional feed rate control.
Option 3 - The OFF mode opens the relay contacts regardless of the flow conditions. The setpoints are not
