5.6.7 Fault Test Push Button

The fault test push button is used to manually change the

mA values to that selected at the 22/3.6 DIP switch.

Pressing this push button for 2 seconds simulates a circuit

test failure. The output goes to the selected fault current of

either 22 or 3.6 mA, and all 3 LEDs go dark. The fault test

push button is an option on both Model 961 and Model 962

in loop-powered configuration only.

5.6.8 22/3.6 DIP Switch

The 22/3.6 switch is used to produce a 22 mA or 3.6 mA

output when the unit detects a fault. The 22/3.6 switch is

on both the Model 961 and Model 962 in loop-powered

configuration only.

5.6.9 PC/LC DIP Switch

The PC/LC DIP switch is used to select pump control (PC)

or level control (LC) mode. In PC mode, the switch func-

tions as a pump controller where the relays latch to enable

an auto fill or auto empty operation. In LC mode, the

switch functions as a level controller where the relays oper-

ate independently of each other. See Section 2.5 of the

Echotel Model 961/962 Ultrasonic Single and Dual Point

Level Switches Installation and Operating Manual (Bulletin

51.646) for proper setting of the PC/LC DIP switches.
