Programmable separately for Alert and Danger alarms. Latching alarms are cleared using the
RESET switch on the System Monitor. Non-latching alarms are automatically cleared when the
monitor no longer detects an alarm condition.
Many 3300 monitors feature latching OK option. The OK relay is reset with the RESET switch on the
System Monitor. If the non-latching OK option is selected, the OK relay will automatically reset
when the
transducer fault clears. When Timed OK/Channel Defeat is used, the OK operation must
be non-latching to allow automatic resetting of the OK relay.
Relays, Normally Energized/De-Energized
The normal condition of a relay corresponds to the non-alarm condition. Normally energized relays
require rack power to hold the relay in a non-alarm condition. Removing the relay's monitor(s) does
not cause the relay to change state. There is no extra cost and no extra tools or parts are required
to change relay operation in the field.
Upscale Toward/Away
Programmable option for monitors that measure position. It defines the direction of the analog
meter indication corresponding to a shaft movement considered to be in normal direction. This
option can be selected per channel. It provides maximum flexibility when defining probe locations
and is especially useful if exact probe locations (orientations) are not known at the time the order is
placed.
