GMC Instruments R2500 Compact Controller with Program Function and Temperature Limiter 48 x 48 mm (1/16 DIN)
The universal, user-friendly compact device in 1/16 DIN format (48 x 48 mm) is well suited for precision control tasks without overshooting, as well as for temperature limiting.
The integrated infrared interface in the front panel and the RS485 MODBUS interface make it possible to configure the controller with CompactConfig software either online or offline, and allows for online viewing of the control process, as well as read-out and storage to memory of values from the data logger and alarm history.
Thanks to IP 67 protection at the front panel, it can be used in machinery and equipment manufacturing, as well as in the food processing and luxury food industries.

Filter and Functions with Distorted Controlled Variable

Parameters

Function
|
Limitation
|
| Peak filter
|
|
Individual erroneous measurements caused by, for example, electrostatic discharge to the sensor, are suppressed.
|
Not active where
Tu < 3 seconds
|
| Smoothing filter
|
|
In accordance with controlled system dynamics, several measured values are combined for control purposes in order to avoid an unsteady controlled variable.
|
|
| Actual value correction
|
Actual value correction, actual value factor
|
Linear correction of measured values if, for example, measured temperature deviates from the temperature to be measured / to be displayed due to a temperature gradient.
|
|
| Adaptive measured value correction
|
On/off with controller configuration
|
Suppression of constant periodic, or slowly changing oscillation.
Not suitable for irregular fluctuation.
|
Not active if period is longer than ½ Tu
|
| Oscillation disabling
|
Oscillation period: 0.3 to 20 s (off = 0 s)
|
Suppression of periodic oscillation with a constant period, if the period is longer than ½ Tu.
|
|
| Feed-forward control
|
Influencing quantity manipulating factor,
controller function
|
Suppression of controlled variable swells and dips in the event of load fluctuations, e.g. caused by operation/standstill of a machine/system
|
Load fluctuation interval much greater than Tu
|
| Response to sensor error
|
Sensor error manipulating factor
|
If operation must be continued with a defective sensor, the controller reads out a plausible manipulated variable if it is useful for maintaining the working level.
As a default setting, the controller is inactive in the event of a sensor error.

Self-Tuning
The control parameters are optimized by means of a specially developed process which can be started at any desired point in time. Control parameters can be changed.
Hot-Runner Control
If this function is used, the controller is forced to follow predefined sequences. This includes, for example, rapidly pulsed read-out of the manipulated variable.
Start-Up Circuit
Actuation with a reduced manipulating factor and dwelling at a specific actuation setpoint serves to dry out hygroscopic heating elements.
Synchronous Heating - Group Actual Value Control
Synchronous heat-up reduces thermal stress within a group of control channels by minimizing dynamic actual value differences. The slowest control system within the group specifies setpoint rise for all other control systems within the group to this end. This is also possible for several devices.
(R6000, R355) Selected setpoint ramps and the actuation circuit are taken into consideration.
Boosting - Temporarily Increased Setpoint
Temporarily increasing the setpoint frees clogged mold nozzles of "frozen" material remnants.
In the case of hot-runner control, the actual control value determines the setpoints of all channels within the group, so that the temperature difference is kept to a minimum. If self-tuning is started at the beginning of the start-up process, for example because another tool with as yet unknown control parameters is started up, the zones are started up with default parameters and the self-tuning sequence is influenced such that no large temperature differences occur during self-tuning.
