Jack,
In a similar vein, if you have alarms that are less important when the
pump (or other piece of key equipment) is down you can connect the
alarm priority -- ie. gland seal is a priority 1 alarm when the pump is
running, but a priority 5 alarm when the pump is off. You can also use
the alarm inhibit mask to selectively inhibit alarms -- ie. pump box
level hi-hi is never inhibited, but hi, lo, and lo-lo are inhibited
when pump is not running.
