Technical information

PANEL ASSEMBLY:
4.1 INITIAL STARTUP:
First remove the mounting clamp and insert the controller into the panel cut out.
Place the unit into the panel cut out and slide the mounting clamp from the rear to
a firm grip at the panel.
When the controller is initially energized the Firmware version is displayed for
approximately 4 seconds in the PV display after which the controller reverts to
normal operation mode or
Operation Cycle
. This is
SET UP Cycle-1
. The upper
display,
PV
, shows the
Process Variable
(temperature) and the lower display,
SV
,
shows the
Set Point Variable
in this cycle. The controller remains in this cycle
while under normal operation.
The internal circuitry can be fully removed from the housing without disconnecting
any wiring. By using the thumb, just press the tab in the lower part of the front
panel, grab the front panel firmly and pull the front face and circuitry from the
housing.
Important: Firmware version of controller must match the version indicated
on the bottom front cover of this manual.
Warning: Use caution when removing the controller from its case, there may
be live voltage present at the terminals. This should only be done by a
qualified technician. It is recommended that power to the controller be
disconnected prior to removing the controller from the case.
4.2 GENERAL SETUP CYCLE PARAMETERS:
The cycles need only to be accessed when a change of parameters is necessary
(except for Set Point change). To reach the other parameters the user must keep
the
SETUP key
pressed for about 4 seconds. After this time the controller will
show the first parameter of the next cycle, i.e.,
Atvn
for Cycle-2. By keeping the
SETUP key
pressed for another 3 seconds the next cycle will be accessed.
3.6 ERROR MESSAGES:
The connection and configuration errors for most of the problems encountered in
using the controller are shown below. A final revision of parameters will save time
and further losses.
Release the
SETUP key
when the desired cycle is reached. Press the
SETUP key
once to go to the next menu parameter in the cycle. The PV display will show the
parameter and the SV display will show the value in the parameter.
Error messages are displayed to help the user to identify possible problems.
: Process temperature is below the selected sensor range.
To change the value of the parameter press the or
keys until the desired
value is reached.
: Process temperature is above the selected sensor range
Cycle Menu System
: Controller or sensor error. Example:
• Broken thermocouple or Pt100.
• Pt100 badly connected, short-circuited or high cable resistance.
4. MENU SYSTEM
The Parameter Menu System is organized into four basic cycles. This is shown in
the chart below:
After the last parameter in one level is reached the controller returns to the
Operation Cycle and the display will indicate the measured temperature.
NOTE: The display will also go back to the measured temperature whenever
the display is inactive for 20 seconds or more.

4.3 DIGITAL SERIAL NUMBER ACCESS:
9
To read the controller’s serial number (8 digits), hold down the key during the
power up. The first four digits will appear in red on the top display, and the second
four digits will appear in green on the bottom display.
The serial number is recorded in the factory and cannot be changed.
