CRelay Outputs

The relay outputs will withstand up to 5 amps at

30 Vdc (resistive load only). They can be used to activate horns and strobes. Refer to Figure 7 for proper wiring. Each relay can be configured in the

PROGRAMMING MENU.

Default setting is:

Relay 1 (J25) = Warn

Relay 2 (J26) = Alarm

Relay 3 (J3) = High Alarm

Relay 4 (J7) = Fault

Relay rating: 5 A, 30 Vdc (resistive load)

DJumper Instructions

The different jumpers on the PCB enable the user to make different operations manually.

Jumper EOL1, EOL2, EOL3, EOL4: Enable the user to add an END-OF-LINE jumper to improve the communication signal. Two positions are possible, R or RC. It can vary in accordance with the system constraints. See the wiring detail for the EOL position.

Jumper SHDN: This jumper enables the user to reset or shut down the microcontroller temporarily. It is mainly used during minor modifications in the wirings of the system.

Jumper RELAY J29, J30, J31, and J32: They are used to test the relay. Short pins to test.
