INSTRUMENT SETTINGS
The instrument comes with a number of factory settings that are good for 90% of cases. However, you can set or edit parame-
ters proceeding as follows
1. Setting or editing of setpoint value
With the burner switched off (thermostat/pressure switch series contacts open, i.e. terminals 3-4 open), press the PGM key,
holding it down for less than 2 sec.. The display at the bottom (green) reads SP1: use the up and down arrows to set the setpoint
value on the display at the top (red).
To confirm the value, press the
PGM
key, then press
EXIT
to return to normal operation.
2. Checking or editing the instrument's PID parameters (table 1 attached)
z
Press the PGM key, holding it down for longer than 2 sec.. The code AL appears on the green display whilst the red display
reads 0
z
reads
0
.
z
To change, use the up and down arrows to change the value on the red display.
z
To confirm, press PGM and the green display moves on to the next parameter.
z
Repeat the previous operations for all parameters.
z
To stop, press the EXIT key.
z
For a list of PID parameters, see table (1) attached.
3. Setting the kind of sensor to be connected to the instrument (table 2 attached)
z
With the instrument in normal operating mode, press the
PGM
key, holding it down for 2 sec.. The instrument enters PID
parameter configuration mode, hence press the
PGM
key for another 2 sec.
z
The green display features the code
C111
whilst the red display gives the code
9030
.
z
Each digit of the code corresponds to a settable parameter
z
When the down arrow is pressed, the first digit on the left (n°9) on the red display starts flashing. Pressing the up arrow
while the digit is flashing, you can change the value according to table (2) attached .
z
Once you have edited the value, press the down arrow again and the second digit from the left (n°0) starts flashing and so
on for all four digits. Press
PGM
to confirm and
EXIT
to exit.
Example: temperature sensor, set
9030
; pressure sensor, set
G030
.
4. C112 and C113 configurations (tables 3 & 4 attached) :
Configurations
C112
and
C113
enable use of an auxiliary contact (terminals Q63-Q64 and LED K6 on the front panel), which is
fully configurable.
It also allows you to choose between degrees Celsius °C or Fahrenheit °F and to lock the instrument's keys.
With the instrument in normal operating mode, press the
PGM
key, holding it down for 2 sec.. The instrument enters PID para-
meter configuration mode, hence press the
PGM
key for another 2 sec..
The code
C111
appears on the green display whilst the red display reads
9030
. If you press
PGM
again, the green display
reads
C112
and the red display reads
0110
.
For the instrument to work as standard, the
C112
configuration should never be altered, whilst the
C113
configuration should be
changed when using pressure sensors or 0-10V / 0.4-20mA signals (see table (5) attached).
5. Configuring process values:
With the instrument in normal operating mode, press the
PGM
key for 2 sec.. The instrument enters PID parameter configura-
tion mode. The code
C111
appears on the green display, whilst the code 9030 (or different code depending on settings made
previously) appears on the red display. If you press
PGM
again, the code becomes
C112
and the red display reads 0010. When
you next press
PGM
, the code becomes
C113
and the red display reads 0110. When you next press
PGM
, the green display
reads
SCL
(=lower limit [instrument range start] for analogue input 1, valid for signals 0-10V, 0-20mA, 4-20mA, 0-100ohms
etc.). Use the up arrow or down arrow to set the chosen value (see table (5) attached).
If you press the
PGM
key again, the green display reads
SCH
(=upper limit [instrument range end] for analogue input 1, valid for
input signals 0-10V, 0-20mA, 4-20mA, 0-100ohms etc.). Use the up and down arrow to set the chosen value (see table (5) atta-
ched).
Example: for SIEMENS pressure sensor QBE2.. P25 (25bar), the input signal used is 0-10V: set
SCL
to 0 and
SCH
to 2500.
That way the instrument's scale ranges from 0 to 2500 kPa (25 bar).
Pressing the
PGM
key repeatedly calls up the following parameters in sequence. These parameters can be edited with the up
and down arrows:
