WR20 Remote Commander

6.9 Autopilot Alarms

The Autopilots are programmed to provide essential alarms. The

alarm message will appear on the WR20, and depending on the

operating circumstances the alarm may inhibit some features of the

WR20 until the alarm condition is cleared.

Note For safety reasons an alarm can only be cleared at the Autopilot

control head itself and not from the WR20 Handset.

An audible alarm will sound on the WR20 for as long as the Alarm

condition exists, or until the user 'Mutes' the Alarm sound or the

condition is cleared at the Autopilot control head.

6.9.1 WR20 Alarm Displays

Once an Alarm 'On' Condition has been received by the WR20, a

pop-up Alarm display will be shown (Fig. 6.14).

If the WR20 was previously controlling the Autopilot pressing the

MUTE SoftKey will silence the alarm, however, the WR20 will

not be usable until the alarm condition is cleared at the Autopilot

control head. If the WR20 was previously controlling an

instrument other than an Autopilot then pressing MUTE SoftKey

will silence the alarm and the WR20 display will return to the

instrument under control. It will not be possible to select the

Autopilot from the WR20 until the alarm condition is cleared at the

Autopilot control head. In both cases, when the alarm is cleared the

WR20 display will briefly show "ALARM CLEARED" before

resuming normal operation.
