PUSH BUTTON TO CANCEL AUDIBLE ALARM

The

CANCEL ALARM PUSH BUTTON

(ITEM 23)

is used to silence the audible

alarm.

Pressing this button once will

cancel an audible alarm that has

occurred

as a result of an:

The

CANCEL ALARM PUSH BUTTON

also used to reset the function kick-out relay

when it is necessary to bypass the function

disconnects. See page 23.

Examples of when it may be necessary to

override a function disconnect condition are:

Overload

A2B

Alarm

If the boom hoist cylinder is fully extended,

the pressure in it will rise. This will be seen

by the system as an overload and will not

allow the operator to boom down. Using the

bypass is necessary in this situation to move

away from the fully extended boom hoist

cylinder position.

Operator Settable Alarm

The audible alarm remains canceled until

the condition that caused the alarm

has been removed.

If a new alarm condition occurs that normally

causes an alarm to sound (such as A2B) or

if a previous condition (such as overload) is

removed and then recurs, the new alarm

condition will cause the audible alarm

to sound again.
