Operation

Avtron Load Bank

The automatic exerciser/controller circuitry within the Load Bank allows for the generator to be

exercised on a programmable, weekly basis.

A programmable weekly timer (K216) is installed on control panel D36083. During a programmed

test cycle, a contact closure from K214 at TB1(17-18) will start the engine generator. K214 is a

"delay-off" relay which, at the end of the programmed exercise cycle, (controlled by K215), will

allow the engine generator to cool down, under a no load condition. When the proper temperature is

sensed, K51 will energize. K51 will initiate the adjustable "delay-on" relays K202, K204, K206,

and K208. These relays control adjustable "delay-off" relays K203, K205, K207, and K209, which

in turn control pilot relays K210, K211, K212, and K213. Each pilot relay controls a portion of the

Load Bank load. Based on the time delay settings of the adjustable relays, a wide range of exercise

control is available. Reference schematic D36028 for sample control scheme.
