Page 2: Primary Applications
Matson Programmable Voltage Sensitive Relay The MPVSR is a ‘solid state’ electronic relay which is activated by sensing the voltage of the circuits it is connected to. The voltages at which it will either open or close are able to be programmed by the user, meaning this product is suitable for a huge variety of applications. - Page 3 FEATURES • Solid state design means no moving parts to fail • Fully user programmable to set voltage and time delays • User programmable to set as either normally open or normally closed • Isolated design means circuit cannot ‘backfeed’ •...

Page 5: Installation
INSTALLATION Correct installation is critical for trouble free operation of the MPVSR. Failure to properly install the unit may cause it to not work correctly, and may also void its warranty. For best results please observe the following instructions. Choose a suitable location where the MPVSR can be mounted. Make sure there is adequate ventilation to allow the unit to dissipate heat, and try to install it in an area that is not too hot. - Page 6 Note: It is very important to use appropriate terminations on your cables. Poor connections can result in overheating, damaging the MPVSR. For advice on termination please contact the place of purchase, an auto electrician, or The Matson Group. See below for termination examples. CRIMP TERMINALS...

Page 7: Initial Setup
INITIAL SET UP Once the control wires are connected to the MPVSR and a power source, the device is ready to be programmed to the user’s desired settings. It is worth keeping in mind that you may not need to alter the factory settings, which are listed in the table below. -

CONTROL PANEL LCD DISPLAY STATE RESET SET SELECTED PUSH BUTTONS TO CONTROL ACTIONS SELECT CONTROL ACTIONS To adjust the settings, observe the following procedure: NOTE; the buttons need to be pressed firmly in the centre or they will not register. This is to avoid accidental changes to programming by bumping the buttons. - Page 9 not need to be changed you can cycle through the parameters using the “UP” and “DOWN” arrows. To change a value: When the value you want to change is displayed on the LED screen, press the “SET” button and the value on the screen will begin to flash. While the screen is flashing, use the “UP”...

Page 10: Common Applications
COMMON APPLICATIONS Dual Battery Charging One of the major uses of the MPVSR is in dual battery charging applications. The MPVSR is used to put the two batteries or banks of batteries into parallel once the primary battery or bank reaches a certain voltage. - Page 11 disconnecting the batteries. If VSR chatter is experienced, increase the delay in 20 second increments. LOWER DELAY IN SECS: This setting determines how long the primary/ starting battery will be allowed to remain at the lower limit in volts before the MPVSR cuts out and isolates the primary/starting battery.

Page 12: Low Voltage Disconnect
Low Voltage Disconnect The MPVSR can be used as a low voltage cut-out device when wired in line between the load and the power source. This would be used in situations where it is important to make sure the power source is not drained too far, like a starting battery in a car, or a lithium battery being used as a power supply. - Page 13 LOW VOLTAGE DISCONNECT WIRING EXAMPLE + SENSE WIRE REMOTE OVERRIDE SWITCH BUZZER MUTE SWITCH (OPTIONAL) LOAD 150A 12 Volt Primary Battery (Sensing)

Page 14: Automatic Paralleling Of Batteries
AUTOMATIC PARALLELING OF BATTERIES The MPVSR can be programmed to connect two batteries or banks together in parallel if the voltage of the primary battery gets to a pre- determined voltage. For example, if the starting battery on a boat was going flat, the MPVSR could automatically connect it to the secondary or house batteries to enable it to start the motor. - Page 15 AUTOMATIC PARALLELING WIRING EXAMPLE + SENSE WIRE BUZZER MUTE SWITCH (OPTIONAL) 12 Volt Primary 12 Volt Secondary Battery Battery (Sensing) (Charging)

Page 16: Automatic Load Switching
AUTOMATIC LOAD SWITCHING The MPVSR can be programmed to perform automatic load switching, by using the control terminals for sensing a desired voltage range. This is particularly useful in remote or unmanned situation where equipment needs to be operated, but also protected from over-voltage and under- voltage damage scenarios. - Page 17 AUTOMATIC LOAD SWITCHING WIRING EXAMPLE FLOAT LOAD SWITCH 150A...
- Page 18 CONVENTIONAL HEAVY DUTY RELAY The MPVSR can be used as a conventional heavy duty relay for switching loads up to 150Amps continuous current at 12VDC. The control device is wired in series with the control wires and activated as required. The voltage settings should be programmed out of any range that would affect operation.
