1. SHUTDOWN BYPASS SWITCH
Manual Start Panels
(S-7.0 and S-7.3)
Hold the switch in the on position for approximately
10 to 20 seconds before starting a cold engine. Hold-
ing the switch on for too long can burn out the glow
plugs. To start the engine the bypass switch must be
held on while moving the engine control switch into
the start position. As soon as the engine starts release
both switches.
Auto Start Panels
(S-7.2, S-7.4, S-7.5, and S-7.6)
When the switch is in the auto start position, the unit
will start upon closure of auxillary contacts. Moving
the switch to the manual position will start the engine
and it will run after the control timers have completed
their sequence.
