To avoid cross interference all low voltage measuring lines and pilot wires must be encased
in a shielded cable (the shielding must be earthed one-sided)
The control leads must be fused externally to protect the output relays.
Phase wire and neutral wire must not be transposed.
Refer to chapter “8.3 Electrical connection diagrams” to connect all cables in accordance to the electrical
connection plan.
4 Controller operation
Default values
Default values for your meter are configured at the factory. The specific values are determined by the options
that were specified on the purchase order. These are provided on the configuration sheet that was shipped with
your meter.
4.1 Putting into operation
Switch on power supply. Digital display and control lamps (if available) will light up according to the setpoint
after some seconds. If nothing happens check the fine-wire fuse (if available) on the back panel of the controller
and the electrical wiring. Adjust set value and check other adjustments.
Operating status
The upper display shows the actual value (channel / measuring input 1), the lower display remains empty
or (depending on the version and settings) shows
the attendant unit of measure (°C, °F, %...)
an additional actual value, the setpoint value or the controller output value Y
or the additional actual value only when the key is pressed.
Alternative type:
Switch over the upper display to the several actual values by pressing the
key, the lower display
shows the number of the attendant measuring input.
Setpoint value setting
Press key shortly (do not hold down)
The upper display shows the abbreviation of the activated setpoint adjustment mode, the lower display
shows the adjusted value.
The indicated value can now be changed by the
(lower) and (higher) -keys.
Each variation of the set value is immediately active, without any more operating steps.
The arrow keys have a built-in accelerator mode: longer pressing causes faster alterations.
Return to operating level
Press key shortly (or automatically after 30 seconds without any key-action)
optional: Press key shortly again: *SP =set values of further control loops (*=no.) /
SP* =further set values of the control loop / SPE =external setpoint (display mode only);
flashing display signifies that the function is not active at the moment
