_______________________________________________________________________
data subjects to alteration 9_E2.DOC /0910527
Installation:
Before installation inspect the controller for any visible signs of damage caused during transport.
Check power supply acc. to name plate.
Push the housing from the front into the DIN- panel cut-out and secure from behind with the
fastening devices supplied.
Electrical wiring:
Plug bar on the back face of the controller; connect up the controller at the rear following the
wiring diagram; wire cross section max. 1,5 mm2
-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.
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.
Maintenance:
All electronic controllers in the product range of the manufacturer are virtually maintenance-free.
Provided that the controller is correctly installed and put into operation and is protected against
mechanical damage and inadmissible operating conditions, it should give years of trouble-free
service. In case of faults repair work by the customer should be restricted to the externally
accessible leads and connections and components the customer is expressly permitted to deal
with himself (bridge circuits, fuses).
All further work, especially on internal components will terminate warranty, makes subsequent
inspection and fault repair more difficult and can cause considerable damage to the circuitry.
For repair remittance remove plug board with connected leads on the rear side,
loosen fastening devices and remove controller from the panel.
In case of remittance please give precise details of the fault to reduce time and cost of repair.
Error messages:
Err 1...6 Fault on measuring input nr. ...
check measuring lines for short circuit or breakage
check measuring input by connecting a RTD
Err 55 Fault on loading the parameter;
press any key, the controller starts in emergency operation mode,
configuration of the parameters has to be checked
Err 50 Hardware error in program section
Err 52 Hardware error in data section
no further operation possible, remit controller for repair
Err 58 Binary inputs out of function (status = 0), remit controller for repair
Err 59 Digital outputs out of function (switched off), remit controller for repair
Err 60 Relay outputs out of function (switched off), remit controller for repair
Err 61 Analogue outputs out of function (0 %), remit controller for repair
Error messages during self adaptation:

Optimization - page 5 -
_______________________________________________________________________
1. manual optimization
An optimum adaptation of the control parameters (P,I,D) is necessary in order to balance
an appearing deviation as quickly, non-oscillating and exactly as possible,
according to the given operating conditions.
Generally these adjustments require a lot of professional knowledge that cannot be replaced
by this brief information.
The following informations are for help purpose only:
P = proportional band Xp (%):
lower value = longer impulses, more sensitive reaction
higher value = shorter impulses, less sensitive reaction
Examples: - Oscillating temperature without distinct initial overshot: Xp too low;
- The setpoint is reached very slowly after initial exceeding: Xp too high.
I = integral action time Tn (min):
lower value= shorter impulse gaps, faster balancing
higher value= longer impulse gaps, slower balancing
Examples: - the set value is reached very slowly without overshooting: Tn too high;
- high initial overshot followed by fading oscillation: Tn too low.
D = rate time Tv (min):
increases the controller reaction in case of fast actual value or setpoint alterations
(adjust only if necessary). Higher values cause higher increase.
2. Self-adaptation
The self-adaptation is an automatic procedure that determines and self-adjusts
the optimum control parameters Xp, Tn and Tv.
Operation, if contained in supply schedule:
(Parameter-safety-switch on the rear panel of the controller (if available) has to be unlocked:
position "u")
Check starting assumptions:
Actual value at least 20% below the adjusted set value,(e.g.:heating phase), otherwise first:
Lower actual value adequately by manual operation (position of final control element) (quick circuits)
or increase setpoint adequately, if admissible. (faster procedure for slower circuits)
Call manual operation level: Press - key plus - key (optional: seperate key).
Check controller output: must not be higher than 85% , reduce if necessary.
Start self-adaptation: Hold down - key for more than 5 sec. on manual operation level.
During operation the lower display shows: "-Ad-",
the upper display still shows permanently the actual value.
Information about computer operation: First the self-adaptation program waits for stabilization
of the actual value according to the given controller output (actual value alteration < 0,1% / min),
then it increases the output signal about 10% or, in case of three- point- step controller operation,
it triggers an output impulse with about 10% of the adjusted regulating time.
The optimum parameters are computed according to the unit- step response.
Cancel: Press - key for more than 5 sec. = return to manual operation level
After successfully finishing the procedure the controller will return automatically
to operating level.
Unsuccessful adaptation ( Display shows error code, ref.to chapter error messages):
Press - key again: Return to manual operation level
eliminate the indicated error
start adaptation again: - key > 5 sec.
or return to operating level: - key shortly
