Alarm A, B, And C Menus; Servicing And Operating Menus - Honeywell 301 Serie Mode D'emploi

Alarm A, B, and C Menus

The screens for viewing alarm thresholds are combined in this manual. There will
be either two or three levels, depending on transmitter type.
If present, separate "MIN" and "MAX" levels permit manual control of the hysteresis
of each alarm. Normally, the "MAX" level is set greater than "MIN." However,
alarms can be made to trigger on falling concentration (as with oxygen) by setting
the "MAX" threshold smaller than the "MIN" threshold.
With certain transmitters, only one threshold will be displayed.
Additionally, with certain transmitters, the alarm thresholds are read-only at the con-
troller. These thresholds can be set only at the transmitter.
These are typical screens: 1. Tx INFO 001
