Introduction
The MTRA-FSP Level Control Relay is a solid-state electronic level control
module housed in a hi-impact plastic case with a DIN rail attachment on the
back. It is used to control pump relays in response to a liquid level sensor such
as a MultiTrode probe. A pump thermal sensor can be connected to the MTRA-
FSP for pump protection. During operation the LED indicators on the front panel
indicate the current status including – Pump On/Off, Thermal Fault, Probe Fault
and Level Alarm.
The MTRA-FSP level control relay is designed to be easy to install and
configure. All connections are clearly labelled on the side of the device and is
configured using a set of dip switches on the front panel.
