In the configuration level the controller type, sensor type, the sensor range, the alarm behaviour and the output type can be pre-selected. This primary information has to be entered before taking the controller into operation. The display of each single parameter within the parameter and configuration levels, and their adjustment, are made in the same way as within the operating level.

After either pressing the „E“ - key for approx. 3 seconds, or waiting for a period of approx. 30 seconds, the unit will automatically return to the operating level (display of process value and setpoint).

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.

Softstart (general function):

So Y Soti

t

During the softstart the controllers’ 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 chosen, 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) is programmed > 0,1%. During the softstart-phase it is not possible to change the setpoint values. For this, the softstart-phase has to be stopped.

Setting: Auto 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 control deviation was more than 0,25% of the total

range at the time of sensor break.

- if the 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 set point display, followed by the output ratio.

- to turn off a control output (setting = 0%).

OPt self tuning OFF self tuning out of action (autotune) on self tuning on request ( one time) Auto self tuning automatically if the controller is switched on and if the difference between process value and setpoint is > 7 % of the range.

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 determined parameters for heating are also adopted for cooling. 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.

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

After having calculated the correct feedback parameters, the controller will lead the process value to the setpoint.

This parameter serves to correct the input signal, e.g. for:

- the correction of a gradient between the measuring point and the sensor tip,

- the line resistance balancing of 2-line RTD (Pt100) sensors and

- correction of the control devition when using P- or PD-action.

If for example the offset value is set to +5°C, then the real temperature measured by the sensor (when process is balanced) is 5°C less than the setpoint and the displayed process value.

(set) are displayed simultaneously (basic setting). If setpoint 1 (SP1) is set to "OFF", the controller switches to stand-by.

The setpoint display then shows "OFF". All main outputs are switched off and the alarm is de-activated. All parameters can be displayed and altered during stand-by.

SP2 Setpoint 2 OFF; SP.Lo SP.Hi (ex works: OFF) The 2. setpoint is active when the external contact K1 is closed. The corresponding LED „SP2“ lights up on the faceplate,and the second set-point is shown in the display.“ Please note, that the value of the second setpoint cannot be changed in the oprating level. In order to change the value the parameter SP2 has to be selected.

AL 3 Alarm 3, Out3 signal contact, setpoint dependent OFF; -999...1000 °K (ex works) OFF; -99,9...100,0 °K

limit comparator, setpoint dependent OFF; 1...1000 °K (ex works) OFF; 0,1...100,0 °K

limit contact, process value dependent OFF; range bottom ... range top

The range of adjustment is dependant on the sensor and the alarm configuration. Both have to be set in the configuration level.

AL 2 Alarm 2, Out2 for adjustments see „Alarm 3“ Alarm 2 is only available, if the controller is programmed as a 2-point- or a continuous-controller in the configuration level.

Er.SY System error Extinguish error signal by pressing the „E“-key. Check all parameters. If the error signal continues please send the controller back for examination.

Installation Instructions

Make certain that the devices described here are used only for the intended purpose. They are intended for installation in control panels. 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). To keep the CE-conformity it is nessesary, to use for sensor- and low voltage signal lines shielded cabels. 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.

IMPORTANT:

Before operation, the unit must be configurated for its intended purpose (e.g. controller type, sensor type and range, alarm adjustment etc.). Please see „Configuration Level“.
