Installation, Operation and Maintenance Instructions
Section 3.2.0. - Pneumatic Level Controller (LCP)
3.2.1.
INTRODUCTION
The LCP Pneumatic Level Switch Controller provides supply and vent air control for two pneumatic switches
used in a high and low point level application. The LCP is designed to be used with pneumatic switches on
magnetic MAG-GAGE® series gages only.
3.2.2. OPERATION
1.
As the float rises past the high pneumatic switch level, it will supply air to the port P4 of the controller.
2.
When port P4 has air supplied to it there will be a pneumatic signal out of port 2 of the controller. The
pneumatic signal will continue until the float passes the low pneumatic switch.
3.
The low switch will supply a signal to port P2 on the controller therefore shutting the pneumatic signal
off. The output signal will stay off until the float rises past the high pneumatic switch.
4.
The cycle will then repeat.
5.
To reverse the output on the controller, connect the high pneumatic switch to port P2, and the low
pneumatic switch to P4 on the controller.
