hold time of zero will be stored. Further beeps each represent 10 seconds of relay
hold time. For example, if the keys are held for a total of seven beeps, this will result
in a hold time of sixty seconds (1 minute). If they are held for a total of thirteen
beeps, this will result in a hold time of 2 minutes.
When the keys are released, a double bleep confirms that the specified time period
has been permanently stored.
Note that the Alarm Relay Hold time can not be set if the SET key is locked out (see
section 7.3). The Alarm Relay Hold time is remembered when he unit is turned off
5.4 Unlatched Alarm Mode
The unlatched alarm mode is suitable for unattended operation as in this mode, the
switcher automatically reverts to normal operation when the alarms end. The audible
bleeper is not sounded in unlatched mode.
5.5 Latched Alarm Mode
The latched alarm mode provides the same facilities as the unlatched mode but
requires that an operator manually cancels the alarm conditions. All alarms will be
remembered by the unit until the SET key is pressed. Only alarms that are still
present will then be acted upon.
If any latched or current alarms exist, an internal bleeper beeps once per second.
