2.6.2 Time Delay Action
TIME DELAY ACTION describes whether the relay
contacts are delayed from going into the alarm state or
recovering from an alarm state.
•
FWD: delays system from coming out of alarm.
• REV: delays system from going into alarm.
• Instrument is supplied with TIME DELAY action set in
forward mode (FWD) position.

2.6.3 Failsafe
FAILSAFE describes the level condition that causes the
output relay to de-energize, and also the state of the relay upon
loss of power.
•
High Level Failsafe (HLFS) is the alarmed condition when
probe is covered. Relay will de-energize when level is high,
indicating high level upon loss of power. (N.O. contacts open
and N.C. contacts closed).
• Low Level Failsafe (LLFS) is the alarmed condition when
probe is uncovered Relay will de-energize when level is low,
indicating low level upon loss of power. (N.O. contacts open
and N.C. contacts closed).
• Instrument is supplied with failsafe jumper set in high
level (HLFS) position.
• Failsafe is field-selectable using a jumper located on sensing
element/ circuit board side of housing.

second SPDT alarm relay.
• Fault: RELAY #2 will de-energize under a fault condition
when AutoVerify™ self-test function is enabled. See
Section 2.6.6
