Press and hold ✱ and use the ▲ or ▼ buttons to select from the choices

Rly,SSd

or

AnLG

depending on the model supplied. SP2 and SP3 outputs will be automatically

allocated. (See output options table on page 8).

4 To enter initial configuration into controller memory

Press and hold both ▲ and ▼ buttons for 3 seconds. The display will now read

PArK

and measured variable (e.g. ambient temperature 23°).

PArK

is displayed because a

setpoint has not yet been entered.

To display setpoint units

Press and hold ✱ The displays will now read

unit

(eg. °C) and

0

To enter setpoint
Press and hold ✱ and use ▲ button to increase or ▼ button to decrease the reading and

scroll to required setpoint value. (The digit roll-over rate increases with time).

THE CONTROLLER IS NOW OPERATIONAL

WITH THE FOLLOWING FACTORY SETTINGS

Proportional band/Gain 10ºC/18ºF/100 units
Integral time/Reset 5 mins
Derivative time/Rate 25 secs

Proportional cycle-time 20 secs
(Typical setting for relay output)
DAC Derivative approach control 1.5
(Average setting for minimum overshoot)

Note: For more precise control or for non temperature applications where a Linear input

transducer is being used, the controller may need to be tuned to the process.
Please refer to the following section on AUTOTUNE.

AUTOTUNE

This is a single shot procedure to match the controller to the process. Select either Tune or
Tune at Setpoint from the criteria given below.

The Tune program should be used for applications other than those listed under Tune at
Setpoint below. The procedure will apply disturbances when the temperature or process

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 in a temperature application

●

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. (see page 5).

GETTING STARTED

After power-up the controller requires programming with the following information:

Type of Sensor (See list of sensors p.22)
Operating unit

°C °F bAr PSi Ph rh SEt

Allocation of Output Device to SP1/SP2 (Relay / SSd) or analogue. SP3 is always relay.
Setpoint

When the above information has been programmed into the controller it will be
operational with factory PID settings.

INITIAL SET-UP

On power-up the controller will display the self test sequence followed by the initial
display

inPt : nonE

1 Select input sensor.

Press and hold ✱ and use the ▲ or ▼ buttons to scroll through the sensor selection

list until the correct sensor is displayed. Release the buttons. The display will now read
selected sensor type e.g.

inPt : tCS

(type S thermocouple).

Press ▲ once The display will now read

unit : nonE

LINEAR INPUT

When Linear Input is selected, the display resolution of the setpoint and many other
functions will be changed from the setting previously made at

di.SP

in Level 2, to that set

at

dECP

in Level A.

It is therefore recommended that on completion of the Initial Set-up the Linear Input
settings in Level A be completed before moving on to configure Levels 1, 2 and 3. (see
Set-up Procedure page 6).

2 Select operating unit.

Press and hold ✱ and use the ▲ or ▼ buttons to scroll through the unit selection list

until the correct unit is displayed. Release the buttons. The display will read selected
unit e.g.

unit : °C

Press ▲ once The display will now read

SP1.d : nonE

3 Select SP1 (Main setpoint output device)

Analogue output

The allocation of the analogue output to SP1 automatically overrides the default
proportional cycle time setting of 20 seconds. Where the analogue output is
allocated to SP2, the default

CyC.2

setting on/off must be manually changed in
Level 1 to a time proportioning setting to enable the analogue output to operate in
proportional control mode.

English

AUTOTUNE (continued)

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 variable

climbs to setpoint.
Note: Avoid tuning while running a program as SP1 may be different from the target

setpoint..

When the TUNE or TUNE AT SETPOINT program is complete the PID values are entered
automatically. The process 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, SSR, valve. A setting that is too long for the process will cause oscillation and 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

(the 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.

A16

. If acceptable, exit program

(▲▼) to implement this setting.

To Pre-select Automatic Acceptance of AUTOTUNE Calculated CYCLE-TIME

Before AUTOTUNE is initiated select

CYC.t

in Level1, press and hold both ✱ and ▼ buttons

until indexing stops at

A

– – . Exit program (▲▼) to accept calculated value automatically.

To Manually Pre-select Preferred CYCLE-TIME

Before AUTOTUNE is initiated select

CYC.t

in Level 1, press and hold both ✱ and ▲ or ▼

buttons until indexing stops at preferred value then exit program (▲▼) to accept.

LINEAR INPUT

Set-up Procedure

The 4–20mA input model converts current into voltage using an internal resistor which
spreads the signal across the input range 10 to 50 mV. using multiplier of 2.5. When using a
transducer with an output less than 4–20mA, the input maximum and minimum mV values
can be calculated using the same multiplier.

Models with 0 to 5V input use an internal resistor to spread the signal across the input
range 0 to 50 mV using a divider of 100. Where a transducer provides a smaller
output, the input maximum and minimum values can be similarly calculated.

Decide what scale minimum and maximum will be required, and whether the scale needs
inverting. (See Level A; Linear Input Scaling for list of settings and limits, page 10).

The example below shows how a 4–20mA linear Input should be configured.

# e.g. 4–20mA = 60 to 260 units where 4mA = 60 units

To align SP2 analogue re-transmission with SP1 control output, select LEVL 2 then:

Set

SP2.A

to

FS.hi

And in LEVL.1

Set

SEt.2

to

50

(ie 50% of display range)

bnd.2

to

100

(ie 100% of display range)

Finally, set SP1 setpoint value as required for process to start.
