Setting the Relay Operation (
relay
)
This menu is used to set up the operation of the relays.
Caution!
During setup, the relays do not follow the
input and they will remain in the state found
prior to entering the Relay menu.
1. Relay assignment
a. Rate for low and high alarm
b. Total for batch control relays
c. Grand total for grand total alarms
2. Relay action
a. Automatic reset only (non-latching)
b. Aut manual reset when not in a batch process (non-latching)
c. Latching (manual reset when not in a batch process only)
d. Latching with Clear (manual reset when not in a batch process only after alarm condition has
cleared)
e. Pump alternation control (automatic reset only, for level applications unrelated to batch
control)
f. Sampling (the relay is activated for a user-specified time and may be assigned to rate or
grand total)
g. Off (relay state controlled by Interlock feature)
3. Set and reset points; batch preset
4. Fail-safe operation
a. On (enabled)
b. Off (disabled)
5. Time delay
a. On delay (0-999.9 seconds)
b. Off delay (0-999.9 seconds)
6. Relay action for loss (break) of 4-20 mA input (ignore, on, off)
Note: Fail-safe should not be used for relays assigned to batch control.
Rate Alarms Only Active During a Batch Process
The rate alarms are active only during a batch process. As a result, rate
alarms should not be programmed with manual reset, as they cannot be
manually reset during a batch process, the only time they are active.
