MOUNTING
To mount a Controller proceed as follows:
1 Check that the controller is correctly orientated and then slide the unit into the cutout.
2 Slide the panel clamp over the controller sleeve pressing it firmly against the panel until the controller is held firmly.
3 The controller front bezel and circuit board assembly can be unplugged from the sleeve. Grasp the bezel firmly by the recesses on
each side and pull. A screwdriver can be used as a lever if required.
4 When refitting the bezel assembly it is important to press it firmly into the sleeve until the latch clicks in order to compress the
gasket and seal to NEMA4X/IP66.
CLEANING
Wipe down with damp cloth (water only)
Note:
The controller should be isolated before removing or refitting it in the sleeve, and electrostatic precautions should be observed
when handling the controller outside the sleeve.

OUTPUT DEVICES
Two of the following output devices are fitted to the controllers, depending on the model.
1 Solid state relay drive (SSd/SSd1/SSd2)
5Vdc +0/-15%, 15mA non isolating
.
To switch a remote SSR (or logic)
2 Miniature power relay (rLY/rLY1)
2A/250V AC resistive, Form A/SPST contacts.
3 Sub miniature power relay (rLY2)
1A/250V AC resistive, Form A/SPST contacts.
OUTPUT DEVICE ALLOCATION
Any of the available outputs may be chosen for the main setpoint (SP1), the remaining device being automatically allocated to the
second setpoint (SP2).
Dual relay or dual SSd output models are available to order. Please contact your local distributor for details.
Designed for use with the following supply voltages:
1). 100 - 240V 50-60 Hz 4.5 VA (nominal) +/-10% maximum permitted fluctuation
2). 12V - 24V (AC/DC) +/-20% 4.5 VA Polarity not required
The supply voltage is dependant on the specific model, check the product label to establish the correct voltage for the unit.
WIRING THE CONNECTOR

THE CONTROLLER IS NOW OPERATIONAL WITH FACTORY SETTINGS
Note:
For precise control of an application the controller may need to be TUNED. Please see the following section on AUTOTUNE
AUTOTUNE
This is a single shot procedure to match a controller to the process. Select either
Tune
or
Tune at Setpoint
from the criteria below.
The
Tune
program should be used when the load temperature is at or near ambient. The procedure will apply disturbances when
the temperature reaches 75% of the setpoint value, causing overshoot which is monitored in order to adjust the
DAC
overshoot
inhibit feature. Care should be taken to ensure that any overshoot is safe for the process.
The
Tune at Setpoint
program is recommended when:
The process is already at setpoint and control is poor
The setpoint is less than 100°C
Re-tuning after a large setpoint change
Tuning multi-zone and/or heat-cool applications.
Notes
:
DAC
is not re-adjusted by Tune at setpoint.
Proportional Cycle Time
can be pre-selected before running the Autotune program.
Hereafter the symbol (
▲▼
) signifies both buttons are held pressed for 3 seconds to ENTER or EXIT program mode.
TUNE OR TUNE AT SETPOINT PROGRAM
Enter program (
▲
▼
) and from the display
tunE : oFF
press and hold
and press
▲
to display
tunE : on
or
tunE : At.SP
Exit program mode (
▲
▼
).
The
TUNE
program will now start. The display will show
tunE
as the process temperature climbs to setpoint.
Note:
During tuning, the main setpoint (SP1) LED will flash.
When the
TUNE
or
TUNE AT SETPOINT
program is complete the PID values are entered automatically. The process temperature
will rise to setpoint and control should be stable. If not, this may be because optimum cycle time is not automatically implemented.
To set the cycle time see
PROPORTIONAL CYCLE-TIME
.
PROPORTIONAL CYCLE-TIME
The choice of cycle-time is influenced by the external switching device or load. eg. Contactor or SSR. A setting that is too long for a
process will cause oscillation or a setting that is too short will cause unnecessary wear to an electro-mechanical switching device.
Factory set -
To use the 20 sec factory set cycle-time no action is needed whether autotune is used or not.
To Manually Select AUTOTUNE Calculated CYCLE-TIME
When AUTOTUNE is completed, enter program (
▲
▼
) and select
CYC.t
in
Level 1
. The display will read
CYC.t:20
(factory setting)
To view the new calculated optimum value, press and hold both
and
▼
buttons until indexing stops. The calculated value will be
displayed eg.
