Fill/Fall Alarm
Fill and Fall alarms share one relay output. The alarm is configured as a Fill
or a Fall alarm with Finch Display jumper J9. The alarm point is settable by
the operator. The Fill alarm is typically used to warn the operator when the
loading process is nearing maximum capacity. The Fall alarm is usually used
when unloading and a minimum volume of product must be retained in the
tank to prevent pump damage. Fill or Fall operation is determined when the
system is installed and is configured inside the Finch Display.
The Finch Display is the source of this alarm. Fill/Fall alarms are indicated by
the flashing the current level on the display and activating the Fill/Fall alarm
relay.
High-High (HH) Alarm
The High-High alarm is set during transmitter programming and is normally
the maximum safe volume of the tank. Dual Rod TD80 transmitters and
probes are settable to a volume from 8” below the tank top and lower while
the Coaxial TD80 transmitters and probes are able to be set from 3” and
lower.
The TD80 transmitter is the source of this alarm. The HH alarm is activated
by a measured volume equal to or exceeding the alarm level set during
programming. High-High alarms are indicated by alternately flashing “HH”
along with the current level on the Display and activating the HH alarm relay.
Spill Alarm
Spill is an approaching overfill condition. Dual Rod TD80 transmitters and
probes are factory set at 7.5” below the tank top while Coaxial TD80
transmitters and probes are selectable in the range of 2.5” down to 15.5”
from the top.
The TD80 transmitter is the source of this alarm. Spill alarms are indicated
by showing “SPill” on the display and activating the spill alarm through the
Spill/Fail (or Fail on the 5332E Displays) relay.
Fail Alarm
System failures such as internal transmitter errors, probe faults or loss of
communications are reported by the Spill/Fail (or Fail on the 5332E Displays)
relay.
The Finch Display reports communication failure. The TD80 transmitter is the
source for all other system errors. Errors are displayed as “E xx”, where xx is
an error code. Loss of communication between the TD80 and Finch is
displayed as “----“.
Alarm Relays
1. Fill/Fall relay
2. High-High relay
3. Spill/Fail (or Fail on 5332E Displays) relay.
