INTRODUCTION
The feature-rich CHS Series Indicating controller is the heart of the EPG Level Master System.
The level is determined by detecting changes in hydrostatic pressure using a submerged stainless
steel pressure transducer. The EPG Level Indicating Controller ‘reads’ the corresponding analog
current and uses one or two of the three internal relays to turn on and off pumps. Pump control
can be either in pump up or pump down modes with either one or two pumps controlled. The
relays can also be used as alarms outputs and can be fully configured for failsafe operation.
The base Model CHS1000 includes features previously listed. In addition to those features, the
CHS1100 and CHS1200 provide even more output, input, and communication options.
The CHS1100 adds an analog output (a re-transmitted, powered 4-20mA), an internal, 24VDC
transmitter power supply and digital inputs (used for pump disable or monitoring pump on/off status
& run time).
The CHS1200 adds RS-232/485 Communications Ports (Modbus). The supply power for each
model can be 24VDC, 120VAC or 240VAC. The CHS Series standard configuration is in inches,
but can be field configured to any other units required.
1.0 Installation
The power requirements for the meter are listed on the label located on the top of the case. Use
only the power indicated. The label also indicates any optional installed hardware that may be
installed. The pre-set factory configuration of the meter is also listed. The settings of the meter
and the alarms can be changed in the field however prior to unattended operation, it is good
practice to confirm all parameters via the display (see configuration guide at end of this document).
1.1 Mounting
The CHS Series mounts in a standard horizontal 1/8 DIN panel opening. The case mounted “ears”
attach to the side of the meter case after it is inserted in the panel. The installation screws supplied
with the meter can then be tightened to secure the meter.
