2 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.

4 Installation
The MTRA-FSP is designed to be mounted onto a standard DIN rail. All power
supply, input and output connections are located on the top of the relay
housing.
4.1 Power Supply
The MTRA-FSP can be supplied power in the following ways:
•85 – 240V AC
•85 – 240V AC with 12 – 30V DC Backup
•12 – 30V DC Supply Only
A switch or circuit-breaker and an overcurrent protection device must be
included in the installation. The disconnection device must be in close proximity
to the equipment and within easy reach of the operator, and be marked as the
disconnecting device for the equipment. The input wiring and the switch/circuit-
breaker/overcurrent device must be rated to at least the nominal input voltage
being used. The recommended current ratings are as follows:
Unit Supply
Range
Recommended Switch/Circuit-
Breaker/Overcurrent Protection
Device Rating
Minimum Supply
Wiring Rating
85-180Vac 0.1A 0.1A
180-265Vac 0.05A 0.05A
12-20Vdc 0.3A 0.3A
20-30Vdc 0.15A 0.15A

5 Operation Modes
The MTRA-FSP can be configured to operate in either Empty (Discharge) or Fill
(Charge) mode.
5.1 Empty (Discharge) Mode
Empty (Discharge) mode is used to pump liquid out of a well once it reaches a
preset level. In this mode the relay operates as follows:
•The pump activates when the liquid reaches the high level probe pump
activation delay period expires.
•The high level alarm probe will operate the Alarm Relay and also the
Pump Relay (in case the high level probe has failed).
•The pump will continue to operate until the liquid level drops below the
low level probe and the pump deactivation period expires.
•A thermal fault will deactivate the pump regardless of liquid level.
•A Probe Failsafe alarm will deactivate the pump regardless of liquid
level.
Note:
Assumed Probe Faults:
If a High Level, or High Alarm input is activated and the Low Level probe
is deactivated, then the relay assumes the Low Level probe is faulty.
In this situation the pump will continue to run for 60 seconds after the
High Level and High Alarm inputs have deactivated. The Probe Fault
LED will turn ON to indicate an Assumed Probe Fault.

5.2 Fill (Charge) Mode
Fill (Charge) mode is used to fill up a well with liquid when the level falls to a
preset level. In this mode the relay operates as follows:
•The pump activates when the liquid reaches the low level probe.
•The low level alarm probe will operate the Alarm Relay and also the
Pump Relay (in case the low level probe has failed).
•The pump will continue to operate until the liquid level rises to the high
level probe and the pump deactivation period expires.
•A thermal fault will deactivate the pump regardless of liquid level.
•A Probe Failsafe alarm will deactivate the pump regardless of liquid
level.
Note:
Assumed Probe Faults:
If a High Level, or High Alarm input is activated and the Low Level probe
is deactivated, then the relay assumes the Low Level probe is faulty.
In this situation the relay will wait for 60 seconds after the High Level
input has deactivated, then start the pump. The Probe Fault LED will
turn ON to indicate an Assumed Probe Fault.
