1. Installing the controller:
1.1 Directions for installation
Important: These directions for the installation of
DOLD devices have to be adhered to:
If these directions are not adhered to the device may not work accurately, be destroyed
or it may result in data being lost.
Read all directions carefully before connecting the device.
Connection to be carried out only by experts.
This device is not a safety device. Safety devices have to be installed according to the relevant
directions for use.
Check if the power-supply voltage corresponds to rated voltage indicated on the identification
plate before connecting and putting the device into operation. Fluctuations in the main voltage
are only admissible within the indicated limits (specifications/identification plate).
The described device is designated for the installation of switchboards.
Electrical connections are to be carried out according to the connecting plan and the directions
of the local electric supply company or the relevant regulations of the VDE respectively.
Other consumers must not be connected to the mains terminals.
In the event of mains interruptions, which lead to a malfunctioning of the device, relevant meas-
ures must be taken to avoid interruptions or interruptions must be filtered out by an external hum
eliminator. The device is equipped with an internal hum eliminator.
On installation the sensor lines have to be shielded. The screen must be single-ended. With re-
gard to thermoelement pick-ups the compensating lead has to be laid as far as the control ter-
minals. The device and inductive consumers as well as sensor lines/signal lines and high ten-
sion lines have to be placed in such a way that any mutual interference is excluded (placed
separately; not parallely laid). go-and-return lines should be laid parallely and, if possible,
twisted.
Non-insulated sensors of a multi-channel control have to be adjusted to the same potential
(max. potential difference: + 3.5 V eff.). Otherwise insulated sensors must be used (Warning:
Ceramics insulations (Al-Oxide) can be conducting >400 °C).
Post-connected contactors have to be equipped with RC protective allocations according to the
manufacturer's instructions. If an internal protective allocation is mentioned in the connection
plan of the device this has to be taken into account in the event of external allocation. If external
allocation is missing short-term voltage peaks may result which lead to faster contact wear and
may cause interference.
The preadjustment of all parameters has to be checked during operation and adjusted to the lo-
cal conditions (installation)! Wrongly adjusted parameters may cause serious malfunctions!
Not all controlled systems can be controlled by parameters measured by means of self-
optimising; therefore, on principle, control response is to be checked for stability.

DOLD GMBH Operating instructions DMP 96 A
DMP 96 A Version: 020 Number of pages: 26
H0e020bA4.doc Edition: 07.11.2006 5
The load circuits of the relays have to be protected against excessive currents in order to avoid
the relay contacts becoming welded together.
The device must not be installed in an ex-area.
If used for purposes other than originally intended the device may be damaged and cause dam-
age to connected installations.
The life time of the relays is limited to 106switching cycles at a load of 500 VA. Thus it is to a
high degree dependent on the frequency of switching cycles.
Time per switching cycle Time after which 106switching cycles are reached
(operation: 8 hours/day at a load of 500 VA)
120 s about 11.4 years
60 s about 5.7 years
30 s about 2.8 years
This table is invalid for Solid-State-Relay.
At low loads life time increases with regard to the values indicated in the table.
The device is to be protected against moisture (especially condensing moisture) and excessive
contamination. If this is not assured the device is liable to malfunctions.
Unplug connecting plugs only longitudinally to plug direction. Under no circumstances must the
connecting plugs be plugged in or out obliquely!
Furthermore care must be taken that the surrounding temperature corresponds to the values
shown in the specifications. Sufficient air circulation must be provided.
These operating instructions do not contain all directions to regulations, standards etc. which
become effective when using this device in connection with other installations. These regula-
tions, standards etc. must be ascertained and abided to by the purchaser.

3.2 Actuator function:
Reconfiguration of the "Aut" parameter makes it possible to use the unit as an actuator (actuator
mode: parameter "Aut" set to OFF on the configuration level)
The
key can be used to switch smoothly back and forth between the control
ler
functions (automatic function) and the actuator (manual function).
The manipulated variable (%) set on the operator or setpoint entry level is relative to the cycle
time (with relay output) or to output deviation (with continuous-action output).
The currently activated function is stored in the EE-PROM. When the unit is powered up it is in
the state of the function last stored.

7. Operation:
The operating structure of the DMP 96 A controller includes six separate levels:
Setting the setpoint (depending on configuration):
•via the operator level.
•via the setpoint entry level (by entering a code).
•the configuration level, where line compensation, range limits, control functions, switching
functions of the limit-value contact, and error allocations are defined.
•the parameterization level, which contains all parameters for adjusting the controller to the
control loop.
•the self-optimization level for setting the correcting setpoint and for starting or aborting
self-optimization.
•the information level for querying current program number and sensor ID.
7.1 Setting parameters on the various levels:
current value: +1
after approx. 3 s: +10
after approx. 6 s: +100
current value: -1
after approx. 3 s: -10
after approx. 6 s: -100
P
display value is accepted
The program returns to normal operating mode after the last parameter has been confirmed.
If no key is pressed within 20 seconds, the program automatically returns to normal operating
mode without accepting any value that has been changed.
After confirming an incorrect code number: Do not press any key for approx. 20 seconds.
Wait for program to return to normal operating
mode.
Enter new code.

How the setpoint is set depends on configuration (parameter ”Co.u” on the configuration level).
The setpoint can be set on the:
•operator level (factory configuration)
•setpoint entry level (setting made by entering a code number).

Important: After any change of configuration or reconfiguration of outputs K 1 and
K 2 (parameters "Co.1" and "Co.2") the corresponding parameters on
the parameterization must be set and adapted to the directly controlled
member.
After any change of configuration or reconfiguration of the setpoint ran-
ge (parameters "rA.H" and "rA.L") the setpoint settings on the operator
level, and the setpoint entry level must be checked and adapted to the
setpoint range.

7.6 The self-optimization level:
The DMP 96 A controller is equipped with an optimization routine for the automatic adaptation of
the controller to the controlled system.
The optimization algorithm is based on modified Ziegler-Nicols rules, according to which the cha-
racteristic data of the system are calculated after an oscillation test in a closed-loop control cir-
cuit.
These characteristic data (particularly period and amplitude of oscillation) form the basis for cal-
culating specific parameters.
Depending on the control function (heating controller or cooling controller), parameters are calcu-
lated for either the heating or the cooling side.
