DUAL-TONE ALARM

Purpose
The dual-tone alarm is an audible alarm system to alert
the operator of the following:
PULSE TONE - Either the engine is low on oil
pressure or the alternator is not charging. Note: On
start-up of the engine it is normal for the alarm to
pulse tone after the glow plugs have timed out until
the engine is running and the oil pressure is up on
the engine.
CONTINUOUS TONE - The engine is overheating.
In either case, when the alarm sounds while operating
the unit, it should be shut down immediately.
Location
DSC-2536
The audible alarm is located behind the engine access
panel on the left side of the unit above the two relays
(Fig. 362).
