Operating level

(for each zone separatly):

Process- and Setpoint value will be displayed simultaneously. Within the operating level the setpoint can be adjusted by pressing the " up " / " down " - keys. Every adjustment has to be quit by pressing the „ E “ - key. All parameters within the operating level ( including the alarm values ) can , in succession, be displayed by pressing the „ P “ - key and adjusted by pressing the " up " / " down " - keys. Quit by pressing the „ E “ - key.

Parameter level

(for each zone separatly):

Within the parameter level the values are adjusted to suit each individual process. This level is reached by simultaneously pressing the "P" - and " E " -keys. The display of each single parameter within the parameter level and their adjustment, are made in the same way as within the operating level. After either pressing the „E“ - key for approx. 1 second, or waiting for a period of approx. 30 seconds, the unit will automatically return to the operating level (display of process value and setpoint).

Configuration level:

This primary informations have to be entered before taking the instrument into operation.

The configuration level is reached by simultaneously pressing the "P" - and " E " - keys for a period of approx. 5 seconds. First choose the configuration level in zone 0. Here general settings have to be made. This has to be programmed at first:

- Only TC- or RTD-connection for all zones? Or: Mixed connection ?

- Alarm configuration (valid for all zones) - Function of key „F1“

- Software key - Serial interface informations

- Heater current monitoring

Than choose the configuration level of each individual controller zone. This has to be programmed at second:

- Controller type (for each zone)

- Input type (sensor type), sensor range (for each zone)

- Min. and max. setpoint range (for each zone) The display of each single parameter within the configuration level and their adjustment, made in the same fashion as within the operating level. There is also a copy function available. So it is possible, to copy the programmed parameters of one zone to other zones. After either pressing the „E“ - key for approx. 1 second, or waiting for a period of approx. 30 seconds, the unit will automatically return to the operating level (display of process value and setpoint).

Please note: In case of sensor error the alarms will react in the same way as range override. The alarm contacts therefore do not offer protection against all types of plant breakdown. With this in mind, we recommend the use of a second, independent monitor unit. Care should be used to ensure, that the setpoints of the alarm contacts are programmed within the selected measuring range. If a setpoint ramp has been programmed, the alarms that are relative to the setpoint (signal contact, limit comparator) follow the setpoint up the ramp.

The following parameters will only be displayed if the heater current monitoring system is activated as descriped below: Heater current monitoring via relay A1: Program parameter Co.A1 to number 8 or 9

Heater current monitoring via relay A2: Program parameter Co.A2 to number 8 or 9 The heater current to be monitored, has to be programed as an absolute value into the operating level for both relays A1 and A2.

See: Operating level, Parameter „A1“ or „A2“. Please note if the supply voltage is low the heater current is higher than the monitoring value otherwise the alarm signal will be

activated. If the heater current value falls below the monitoring value, an alarm signal (the relay switches) will be activated. With the help of the parameter „dL.Ax“ it is possible to program a delay time. If you do so, it is virtually impossible to get an unauthorized alarm signal. When switching the power-on, the alarm signalisation will be suppressed until the heating current values for all zones has been scanned and verified. The monitoring function and all possible adjustments are valid for all connected heating zones.

Softstart-function

TAKE CARE: If you take the softstart-function, make sure that the heating control outputs are

equipped with bistable voltage (logic) outputs. This function is not allowed for instruments with relay-outputs (in this case set So.St = OFF). Otherwise the relais will be destroid becuse they switch too fast.

Softstart (general function):

During the softstart the controllers’ heating output response is limited to a pre-selected ratio, in order to achieve a slow baking out of high performance heat cartridges. Simultaneously the output clock frequency is quadrupled. Once the process value reaches the softstart setpoint, it remains stable at this value for a pre-selcted hold-duration time. At the end of this period the process value rises to the valid setpoint. This results in a slower, more regular heating period. For this purpose the bistable voltage output must be taken, that actuates SSR relays. If the softstart is active, the controllers’ autotune function can’t operated (Er.OP). If a setpoint-ramp has been programmed, the softstart has priority, and the ramp will only become active after the softstart has been completed.

The softstart only works,

- if the parameter „1 P“ (prop. band, xp) is programmed > 0,1%.

- if the actual process value is lower than So.SP – 5% of the selected measuring range. It is possible, to select this function for each zone individally.

In event of sensor break the controller automatically maintains the

last valid output ratio as the actuating signal.

An „H“ is then displayed as the first digit in the setpoint display, followed by the valid output ratio. This ratio can be manually altered in steps of 1% (up/down-keys; enter). Under the following circumstances, the output ratio will be 0%:

- if the output ratio at time of the sensor break was 100%.

- if the controller is working along a setpoint-ramp.

- if the control deviation was more than 0,25% of the total range at the time of sensor break.

- if th prop. band (P; xp) = 0.

- if the soft start was active at the time of the sensor break. A few seconds after the sensor break has been rectified, the controller returns to automatic operation and calculates the required output ratio. An additional signal can be issued in the event of sensor break, if the alarm contacts are programmed accordingly.

Setting: Man

The controller now operates only as an actuator. Within the operation level, an output ratio can be entered instead of the setpoint. An „H“ is then displayed as the first digit in the setpoint display, followed by the output ratio. There is no controlling action.

OPt self tuning OFF self tuning out of action (autotune) on self tuning on request ( one time)

The tuning algorithm determines the characteristic values within the controlled process, and calculates the valid feedback parameters ( P,D,I ) and the cycle time ( C = 0.3 x D ) of a PD/I-controller for a wide section of the range.

The self tuning activates during start-up shortly before the setpoint is reached. The setpoint must amount to the least 5% of the total range. If activated after the setpoint has already been reached, the temperature will first drop by approx. 5% of the total range, in order to detect the exact amplification of the process.

Using the heat-cool controller, the temperature drop will be accelerated by switching on the cooling for a short duration. The tuning algorithm can be activated at any time by selecting the OPT=on and pressing the „E“-key. Zone display: During self tuning „OPt“ is shown in the display, alternating with the setpoint value.

The controller must be installed so that it is protected against impermissible humidity and severe contamination. In addition, make sure that the permitted ambient temperature is not exceeded.

The electrical connections must be made according to the relevant locally applicable regulations.

If using a thermocouple sensor, the compensation cables must be laid directly to the controller terminals. Transducers must be connected only in compliance with the programmed range. Transducer cables and signal lines (e.g. logic or linear voltage outputs) must be laid physically separated from control lines and mains voltage supply cables (power cables) and must be shielded. Spatial separation between controller and inductive loads is recommneded. Interference from contactor coils must be suppressed by connecting adapted RC-combinations parallel to the coils. Control circuits (e.g. for contactors) should not be connected to the mains power supply terminals of the controller.
