Relay A can be configured for the following operations
- Response to rising or falling process values
- Adjustable on and off set-points
- Cycle on and off times
- Failsafe operation
TO CYCLE ON
The relay can be set to control either a
RISING or FALLING process.
In a FALLING process, the control relay
will energize when the process falls
below a set value. In this case, the ON
set-point must be set lower than the
OFF set-point.
In a RISING process, the control relay
will energize when the process rises
above a set value. In this case, the ON
set-point must be set higher than the
OFF set-point.
The RELAY ON setting is the process
value at which the relay will energize. It
may be set anywhere between 0-100%
of the range.

The RELAY OFF setting is the process
value at which the relay will de-energize.
The setting must be rationalized against
the On setting. For example, in a falling
process, the Off setting must be higher
than the ON setting.
The controller will not allow you to select
the RELAY OFF value on the wrong side
of the RELAY ON value for the selected
direction. If the user tries to set the
RELAY OFF on the wrong side, the
following errors will de displayed:
Error when trying to set OFF point lower
than ON point when set to falling.
Error when trying to set OFF point higher
than ON point when set to rising.
