165 RBX ALARM ENABLE Code (0-1) to determine the type of instrument alarm operation.
When the RBX function (Report By Exception) is disabled, all
instrument alarms operate as in previous versions of firmware, i.e.,
alarms stay active until manually cleared. When RBX is enabled,
instrument alarms are automatically cleared after the alarm
parameter returns to its normal operating range, buffered by a user-
specified dead band. Exceptions; A/D Fault andSwitch Faults
1 & 2. “Alarm”, “Alarm Ack” and “Alarm Clear” entries are time-
stamped into the Alarm Logger to provide details of alarm activity.
Also see Items 237 & 174 for related functions.
Select: 0 - Standard Alarms------Default
1 - RBX Alarms
166 PCOR PRESS DEAD BAND A hysteresis band that provides a buffer below the PCor Pressure
Hi limit (item 010) and above the PCor Pressure Lo limit (item
011) when alarms are automatically cleared by RBX operation.
The user-specified value determines the magnitude of the band.
The PCor pressure measurement (item 008) must pass completely
through the dead band before the pressure alarm is automatically
cleared.
Default = 5.00 PSIG
167 TMP DEAD BAND A hysteresis band that provides a buffer below the Gas
Temperature Hi limit (item 028) and above the Gas Temperature
Lo limit (item 027) when temperature alarms are automatically
cleared by RBX operation. The user-specified value determines
the magnitude of the band. The temperature measurement (item
026) must pass completely through the dead band before the
temperature alarm is automatically cleared.
Default = 10.00 F
168 BATT DEAD BAND A hysteresis band that provides a buffer above the Battery Low
Limit Voltage (item 049) when the main Battery Low alarm is
automatically cleared by RBX operation. The user-specified value
determines the magnitude of the band. The battery voltage
measurement (item 048) must pass completely through the dead
band before the battery low alarm is automatically cleared.
Default = 1.00 Volt
