WARNING: The MTRA-FSP installation and wiring must be performed by qualified personnel. Danger: The MTRA-FSP has no user serviceable parts. To reduce the risk of electric shock, leave all servicing to qualified MultiTrode technical staff. Page 4 of 16 00242600-MTRA-FSP_Manual.doc...
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 –...
MTRA-FSP Installation & Operation Manual 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. Power Supply The MTRA-FSP can be supplied power in the following ways: 85 –...
MTRA-FSP Installation & Operation Manual DIP Switch Settings The MTRA-FSP is configured using the DIP switches located on the front of the relay enclosure. DIP # Setting Mode Description See Section: Empty (Discharge) Mode Fill (Charge) Mode High Level Alarm Low Level Alarm 0.5 sec Pump Activation and Deactivation...
MTRA-FSP Installation & Operation Manual Operation Modes The MTRA-FSP can be configured to operate in either Empty (Discharge) or Fill (Charge) mode. Empty (Discharge) Mode Empty (Discharge) mode is used to pump liquid out of a well once it reaches a preset level.
MTRA-FSP Installation & Operation Manual 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.
• Flashing alarm output (DIP Switch ON) • Pump Alarms There are two types of pump alarms supported by the MTRA-FSP – Thermal and Seal. 6.2.1 Thermal Alarm Input A pump thermal sensor can be wired into the Thermal input. This is used to detect when the pump is overheating due to a blockage or other fault.

6.2.2 Thermal Backup (BU) Input The MTRA-FSP can be used as a backup pump control device for the MultiSmart Pump Controller and RTU. When used as a backup, the Thermal sensor is wired into the Thermal input, and the MultiSmart Thermal input is wired into the MTRA-FSP Thermal BU input.
MTRA-FSP Installation & Operation Manual Manual (Hand) and Off Inputs The MTRA-FSP can manually operate a pump using pushbuttons wired into the Manual (Hand) input and the Off input. Manual Operation of Pump (Hand) Manual pump operation works as follows: Pushing the Manual (Hand) button will start the pump.
Advanced Settings Probe Sensitivity The MultiTrode Probe is a conductive level sensing device that relies on conductivity through the liquid to earth in order to detect level. For most common applications the default probe sensitivity setting of 20kohms will work correctly.
