One press (press and release) will cause the system to execute a self-test routine at any time. All lamps,
audible alarms, and digital displays will be functionally tested and all memory areas checked for accuracy
during a self-test. If faults in the system are detected, the information area in the upper display will show
the word "
FAULT
." If the word FAULT occurs,
press
and
hold
the TEST button. This will cause the
display to change to the FAULT MODE. In this mode, information about the fault condition will be
displayed in the upper right display via an error code.

CANCEL ALARM
The CANCEL ALARM button is used to cancel the audible alarm after the alarm has occurred as a result
of an OVERLOAD, an ANTI TWO-BLOCK ALARM or an OPERATOR SETTABLE ALARM. The audible
alarm may be canceled by pressing and releasing the CANCEL ALARM button.
The audible alarm remains canceled until the condition causing the alarm has been removed.
For example, if the audible alarm was canceled because of an overload condition, it will remain canceled
until the overload condition is removed. However, if a different alarm, e.g. an anti two-block condition,
occurred when the audible alarm was still canceled for an earlier overload condition, the new alarm
condition would cause the audible alarm to be restarted.

CANCEL ALARM
is also used to reset the function kick-out relay when it is necessary to by-pass
function kick-out that has occurred as a result of either an overload or an A.T.B. alarm. The relay is
re-set by first canceling the audible alarm [as described above] and then pressing and holding the
CANCEL ALARM button for about 3 seconds. The function kick-out relay will then be set to normal
operation. However, should another different alarm condition occur when the relay had previously been
overridden, then the newly occurring alarm condition would cause the motion cut to be re-started.
CANCEL ALARM
is a temporary function. The audible alarm or function kick-out is automatically reset
when the condition, which caused the alarm, is no longer present.
