FROM CYCLE ON

The CYCLE OFF time is the amount of time in
seconds that the relay will be off for, it can be set
between 0 - 600 seconds.

To disable the cycling feature set the cycle off
time to 0.

The Default OFF time is 0 seconds.

The OVERFEED TIMER is designed to help safeguard against
a process or instrumentation error causing one of the control
relays to remain energized for extended periods of time.

When enabled, the user must select the desired overfeed
timeout time (1-999 min.)

If the overfeed timer times out:
• Alarm relay will energize.
• Control (A&B) will de-energize
• LED on front will flash

Must be reset via Utilities Menu or Power reset.

The FAIL SAFE feature is designed to reverse the normal action of
the relay.

When set to FAIL SAFE OFF, the relay will operate as a normal
relay, which means that when the relay is not energized the NO
contacts are open, and a device connected via the NO contacts is
turned off. When the relay becomes energized the device turns on.

When the relay is set to FAIL SAFE ON, the normal action of the
relay is reversed. Thus the NO contact acts as the NC contacts and
the NC acts as the NO. Therefore the device connected to the NC
contacts will be turned on when the relay on set-point is reached.
Actually the relay will be de-energized but because it is acting in
reverse the device will be turned on. When the relay off set-point is
reached the relay will energize and the device connected to the NC
contact will turn off.

The reason that the Fail Safe option would be used is to have the
device turned on in the event of a power interruption.

With "N" selected, pressing the
key will NOT store the selection, but
simply return to the OUTPUTS Menu.
This function is useful if you wish to view
the current selection without making any
changes.

The relay can be set to CYCLE when the process
is between the RELAY ON setting and the RELAY
OFF setting. This is meant to help eliminate
overshoot.

The CYCLE ON time is the amount of time in
seconds that the relay will be on. The value can be
set between 0 and 600 seconds.
The default ON time is 5 seconds.
