SPECTRUM™ TS Operation

Viewing and Clearing Alarm
Codes

Alarms may be one of four types as shown. If an
alarm applies only to a specific zone, that zone
will be displayed with the alarm code.

Log Alarms:

are indicated at the top of the

Standard Display for 30 seconds each time the
unit is turned on. The alarm indication will go off
after 30 seconds. The Alarm Display must be used
to view the existing alarms. This level of alarm
serves as a notice to take corrective action before
a problem becomes severe. Maintenance items
such as maintenance hourmeter time-outs are log
alarms.

Check Alarms:

are indicated at the top of the

Standard Display with the statement [SERVICE
REQUIRED WITHIN 24 HOURS]. The Alarm
Display must be used to view the existing alarms.
This level of alarm serves as a notice to take
corrective action before a problem becomes
severe. The unit will run with check alarms but
some features and functions may be inhibited. If
an alarm applies only to a specific zone, that zone
will be displayed with the alarm code. On a
multi-temp application if a zone specific problem
is severe the zone will shut down but the alarm is
set as a check alarm to allow the other zones to
continue to run. If severe problems occur in all
zones the unit will shut down.

Prevent Alarms:

are indicated at the top of the

Standard Display with the statement [UNIT IN
PREVENT MODE]. The Alarm Display must be
used to view the existing alarms. The unit may
wait a timed restart interval or until conditions
allow and then restart. If the unit is in a restart
interval Alarm Code 84 Restart Null will be
present along with the Prevent Alarm. In other
cases the unit may restart or run with reduced
performance to determine if continued operation
is possible. If the alarm does not reoccur with
reduced performance the unit will then return to
full performance. If the unit is operating with
reduced performance Alarm Code 85 Forced Unit
Operation will also be present. If the alarm
condition reoccurs a set number of times the alarm
is set as a shutdown alarm and no further restarts
are possible. If an alarm applies only to a specific
zone, that zone will be displayed with the alarm
code.

Shutdown Alarms:

replace the Standard Display

with a flashing Alarm Display and the statement
[UNIT NOT RUNNING – SERVICE
REQUIRED].

The flashing display shows the alarm that caused
the shutdown. Shutdown alarms will force the unit
into shutdown. The unit will remain in shutdown
until the shutdown alarm is cleared. Exceptions
are some engine and electric shutdown alarms that
become log alarms when switched to the alternate
operating mode (diesel to electric or electric to
diesel).Special Considerations

Pretrip Alarm Codes:

If an alarm occurs during a

Pretrip Test the alarm code will be displayed as
Pretrip Alarm XX, where XX is the alarm code.

Alarm Codes and switching modes from diesel to
electric or electric to diesel:

If a shutdown alarm occurs that affects only diesel
mode operation and the unit is switched to
electric, the diesel mode shutdown alarm becomes
an electric mode log alarm. This allows the unit to
run in electric mode without clearing the
shutdown alarm that is preventing diesel mode
operation. If the unit is switched back to diesel
mode, the alarm again become a diesel mode
shutdown alarm and prevents unit operation. In
the same manner, if a shutdown alarm occurs that
affects only electric mode operation and the unit is
switched to diesel, the electric mode shutdown
alarm becomes a diesel mode log alarm to allow
diesel mode operation. If the unit is switched back
to electric mode, the alarm reverts to an electric
mode shutdown alarm and prevents unit
operation.

Displaying and Clearing Alarm
Codes

Alarms are displayed and cleared using the Alarm
Menu. From the Standard Display, press the
MENU key.
