Overfeed Timers

8.3 Overfeed Timer

“Timeout” Operation

The useful relay overfeed timer feature, 

only available to a

CONTROL relay

, is described in detail in this section.

Suppose that you configure a CONTROL relay with a high
phase to operate in response to increasing measured value.
The CONTROL relay will then turn on whenever the meas-
ured value exceeds its preset setpoint. When the measured
value decreases below the setpoint by an amount you pre-
set (the deadband setting), the relay will turn off. But what if
a damaged sensor or a process upset condition keeps the
measured value above the setpoint or deadband setting?
The control element (valve, pump, etc.) switched by that
relay would then continue to operate. Depending on the ap-
plication control scheme, this may excessively dispense
costly chemical additives or overly drain or divert the proc-
ess. Also, the control element itself could be damaged due
to excessive continuous or unusual operation such as a
pump that is running dry. The useful overfeed timer pre-
vents undesirable conditions like these from happening. It
restricts how long the relay and its connected control ele-
ment will remain on regardless of conditions.

To set a relay overfeed timer, refer to PART THREE, Sec-
tion 5.3 in the “Relay Setup” subsection. The time you set to
restrict how long the relay stays on (0-999.9 minutes)
should be just enough to provide acceptable results. An ex-
cessive setting may waste chemicals or the process itself.
Initially, set this time as an estimate. Then, by experiment-
ing and observing the response, periodically “fine tune” to
optimize the setting.

When a relay overfeed timer “times out,” it:

•

  Turns relay off until overfeed timer is reset.

•

 Adds “Overfeed (A, B, C) Timeout” Fail message (#91,

#93 and #95 respectively) to message list and logbook,
and TTL NAMUR Output C (if used) responds to this
condition by turning on.

•

  Changes Analog Output 2 (only when set to represent a

dedicated non-variable alarm signal) to the selected
alarm state value (4 mA or 20 mA).
