ALARMS & ERRORS

INTRAC-305

SECONDARY ALARMS

There are three Secondary Alarms :-

Unable to Predict Alarm.

Beacon Alarm.

Servo Alarm.

Unable to Predict

This alarm is raised when the INTRAC has not enough

 

confidence in the orbit model to be able to predict the

 

satellites position. e.g. during the early part of learning a new

 

model or after there had been no beacon signal for more than

 

72 hours.

Beacon Alarm

The Beacon Alarm is raised when the signal strength does

 

not vary during step cycles or when beacon lock is lost.

Servo Alarm

The Servo Alarm is raised when the INTRAC fails to detect

 

the expected amount of antenna movement during a step

 

cycle. This can be caused by the servo performance not

 

corresponding to the routine’s model of the antenna drive

 

characteristics. The INTRAC reacts by repeating the step

 

cycle with a larger drive demand.

 

Secondary Alarms do not, necessarily, mean that there is a

 

system fault nor do they illuminate the System Alarm

 

indicator. The occurrence of a secondary alarm may be

 

checked by selecting Show Alarms in the Home menu.

ALARM OUTPUTS

Three sets of changeover relay contact outputs are available

 

on a 25-way D-type connector on the INTRAC rear panel.

 

There is one relay for a Primary Alarm, one for a Secondary

 

Alarm and the third indicates that the beacon signal has fallen

 

below the user set beacon threshold.

RECOVERING FROM ALARMS

All Primary Alarms, except the Hardware Alarm in Auto Mode,

 

cause the unit to be put into Standby Mode. Recovery from

 

Drive Fail, Synchro and Hardware (other than when in Auto

 

Mode) Alarm conditions are cleared by pressing any Mode

 

selection key (eg Standby). Soft Limit and hard limit alarms

 

can only be cleared by driving back from the limit using

 

Manual Mode. Emergency Stop and Interlock alarms can

 

only be cleared by removing the cause of the alarm.

 

If a Hardware Alarm occurs when the INTRAC is in Auto

 

Mode the unit will perform a processor reset and then enter

 

learning mode to re-learn the orbit model.
