Operation
It allows Mode Selection during Run mode,
while it allows saving value of a parameter
inside a mode. When inside any mode, it
allows to enter in sub-mode.
It is used to come out from mode/Sub-
mode. It is also used to escape from edit
mode without saving the respective
parameter.
It is used in increment of value in run mode
and other modes
It is used in decrementing value when run
mode and other modes. It is also used for
shifting a digit while editing of numeric
value.
It allows user to toggle between Auto
Channel Display mode – Manual Channel
Display Mode.
Acknowledge the Alarm During RUN Mode.
Enter into Set Alarm1 and Alarm2 mode
during RUN Mode
When pressed in run mode it will allow the
user to enter into Control Set point Mode
Control Output Operation
Control O/P is the simplest form of temperature control.
The output from the device is either on or off, with no
middle state. For heating control, the o/p is on when the
temperature is below the set point, and off above set point.
Since the temp. crosses the set point to change the o/p
stage, the process temp. will be cycling continually, going
from above set point to below, and back above. In cases
where this cycling occurs rapidly, and to prevent contactors
and valves from getting damaged, on-off differential, or
Hysteresis is added to the control operations.
This Hysteresis assures, if temp. goes below set point by a
certain amount before then only o/p will turn off or on
again. On-Off Hysteresis prevents the o/p from chattering
or making fast, continual switches if the cycling above and
below the set point occurs very rapidly. Once Process value
reaches down to set point-Hysteresis value relay will be
energized and it will be on until process value goes up
towards Set point.
BASIC DO (DIGITAL OUTPUT) FUNCTION
WATCHDOG TIMER / OUTPUT OPERATION
The WDT, when enabled, operates from the internal Low-
Power RC (LPRC) Oscillator clk source. The WDT can be
used to detect system software malfunctions by resetting
the device if the WDT is not cleared periodically in
software. If malfunctioning of device persist even after
watchdog reset device will go into shutdown mode followed
by error messages on display as per Error! Reference
source not found..
Device Fault can be monitored by a failsafe relay o/p which
is mapped for watchdog o/p.
When WDT is disable device
will continue to work with fault. The Fault LED will be on in
this condition.

Set Point) and 1 for Control Set Point, totaling 48 alarm
outputs and 24 control outputs for 24 number of channels.
Control Outputs are Optional.
8 Relays and/or 24 Open Collectors can be used as DO.
All Digital Outputs are Optional.
