A closer look at the circuit below will reveal some of the unique features of the LSI-55 R Load Status Indicator. With a supply voltage of 10 to 300 Volts AC or DC and the circuit breaker engaged (not tripped), the Load Status Indicator, LSI-55 R and the Remote Pilot Indicator, LSI-55 P will illuminate Green, indicating that power is available to operate the load. In this example the load is a simple lamp, but a motor or heater or any type of electrical load that draws less than 30 Amps can be used.
With the Load Status Indicator, LSI-55 R and the Remote Pilot Indicator LSI-55 P illuminating Green, power is available to operate the load and the switch can be placed in the on position to turn the lamp on. If all is OK with the lamp and the wiring to the lamp, the Load Status Indicator, LSI-55 R and the Remote Pilot Indicator, LSI-55 P will illuminate Red, indicating the load is active and that the lamp is drawing current (greater than 1.0 Amps). If the LSI remains in the Green state then one of two possibilities exist. The wire to the lamp is defective or the more probable cause, the lamp is "burned out".
The Pilot Indicator LSI-55 P can be installed several hundred feet from the Load Status Indicator, LSI-55 R. The signal wires (blue) carry a maximum of 10 mA, a 3 conductor 22 AWG is ideal (General Cable/Carol C4062A-12-10 W).
The Load Status Indicator, Model LSI-55 R is similar to the LSI-55 with the added feature that the LSI-55 R supports the remote Pilot Indicator, LSI-55 P and the Data Module, LSI-55 D. With only 4 terminals (see typical application below), 2 that are .250 quick fit male tabs for supply and load and 2 that are .110 quick fit male tabs for connecting to the remote Pilot Indicator, LSI-55 P and the Data Module, LSI-55 D .
