Controller Types

Controller Type Applications Measure (Cout = MEAS) This configuration is intended for temperature monitoring.
Actuator (Cout = POW) Same as controller type 1 (measure)
Limit transducer (Cout = OnOF)
PDPI controller and PDPI step-action controller (Cout = PdPI )
Proportional actuator (Cout = ProP)
GMC-I Messtechnik GmbH R2500–19
Limit value monitoring can be configured. System deviation is not used for any other purposes.
In addition, the actuator manipulating factor is read out with the actuating cycle. The maximum manipulating factor is read out if the actual value is less than the momentary setpoint. The minimum manipulating factor is read out if the actual value is greater than the momentary setpoint plus the
dead zone. Switching hysteresis is adjustable, and status changes are possible after each actuating cycle. Actuating cycle time is used as a time constant for an additional input filter. The PDPI control algorithm assure short settling time without overshooting. The actuating cycle is at least as long as the selected value. The dead band inhibits switching back and forth between “heating” and “cooling” if no lasting deviation occurs. Selection of these two controller types, namely PDPI and PDPI step-action controller, defines the controller
itself on the basis of the output configuration. The control variable is proportional to system deviation, and a statistical dead zone can be adjusted at the
cooling side. Actuating cycle time is used as a time constant for an additional input filter. This controller type is not intended for temperature regulation, because it does not demonstrate the dynamics
required for control without overshooting.
GMC-I Messtechnik GmbH R2500–20

Conversion of Parameter Sets

If the binary input is configured to parameter set conversion (SEt2 ), parameter set 2 is loaded when the contact is closed, and paramter set 1 is loaded when the contact is open. The active configuration is overwritten in each case. The W2 LED lights up when parameter set 2 and/or 3 is active.

Backup Functions

If the binary input is configured to backup function (bACK), the momentary actual value is adopted as setpoint value when the contact is closed. Control is inactive and the manual operation LED lights up.
When the contact is open, control is effected with the adopted setpoint value according to configuration.

PI Performance

The differential component of the PDPI controller type can be attenuated to such an extent by activating PI performance (configuration: PI = YES) that practically no more derivative action occurs. As opposed to a pure PI controller, response to setpoint changes can be configured without overshooting. This setting is advisable for control systems which include true delay time.

Extra derivative action for cooling

In controlled systems in which cooling has much better or worse thermal contact than heating, control performance for a cooling work point can be improved by setting the tu II configuration to EnA. This makes it possible to set the delay time for cooling (parameter tu II ) independently. In the case of water cooling, half the derivative action is automatically used for cooling when configuration tu II = diS has been selected.

Configuring the Switching Outputs and the Continuous Output

Switching output out1 is configured with a 2-step heating controller as a standard feature (relay or transistor output, depending upon variant). Control performance (2-step heating or cooling, 3-point discontinuous, step-action controller, continuous-action controller, split range controller) is determined by the configuration selected for the actuating outputs. See also the “Configuration” table on page 16. – Actuators for heating and cooling are selected independent of each other. – If 2-step control is required, heating and cooling outputs may not be configured simultaneously for the respective controller. – Both switching outputs can be assigned to the same controller output for separate control of several actuators with a single controller output. – If a continuous and a discontinuous output are both configured for heating (or cooling) at the same time, the channel performs like a
continuous-action controller and the discontinuous output is inactive.
– If, inadvertently, only one “Less” output is configured for heating (or cooling), it remains inactive. – Settings can be freely combined regardless of controller type.

Relay Outputs for Actuating Signals

If two relay outputs are required for the actuating signals, for example in the case of three-step or step-action control, the alarm outputs can be exchanged with the actuator outputs. The Out = XCh configuration (see page 16) exchanges the functions of out1 with A1 and out2 with A2.
GMC-I Messtechnik GmbH R2500–21
GMC-I Messtechnik GmbH R2500–22

Actuator Output for Contactor

If, during ascertainment of control parameters (manual optimization or self-tuning), a cycle time results which is significantly shorter than advisable for the service life of the contactor, cycle time can be increased to the limit of system controllability by configuring the actuating outputs for contactor control (rELA = YES). If the bit is set before self-tuning is started, cycle time is set to the highest possible value by the self-tuning function.

Water Cooling

In order to account for the disproportionately powerful cooling effect which prevails when water is evaporated, the cooling control variable can be read out in a modified fashion by configuring the switching output for water cooling (Outx = H2O).

Configuration of the Controller with Continuous Output

Switching back and forth between current output and voltage output is automatic based upon load impedance.
Continuous output = heating or cooling Cont = HEAt or CooL
Continuous output = controlled variable or setpoint Cont = Proc or SP
The manipulated variable is read out within a range of 0 to 100% depending upon controller type.
The momentary controlled variable of the currently valid setpoint is read out. The read-out is scaled with the rnL and rnH parameters.

Setpoint Ramps

Function The parameters SPuP / SPdn cause a gradual temperature change (rising / falling) in degrees per minute.
Activated by: – Switching auxiliary power on – Changing the momentary setpoint, activating setpoint 2 – Switching from manual to automatic operation
Setpoint display The targeted setpoint is displayed (not the currently valid setpoint) with a blinking r at the left-hand digit. Limit values Relative limit values make reference to the ramp, not the targeted setpoint. As a rule, no alarm is triggered for this reason.

Suppression of Periodic Disturbances

If the measured value is superimposed with highly periodic oscillation which, for example, occurs due to cyclical withdrawal of energy from the control loop, the manipulated value may fluctuate between its extreme values resulting in unsatisfactory control results.
If the period is constant, this oscillation can be filtered out by setting the period in the oscillation suppression tSUP parameter. This is accomplished by means of narrow-band filtering in order to remove the signal component with the selected period, which is then disregarded for measuring signal control. The actual values for the display are not influenced. As opposed to adaptive measured value correction (see also page 24), oscillation can also be suppressed with this function whose periods are greater than half of the system’s delay time.
Periods can be selected within a range of 0.3 to 25 seconds, and the filter remains inactive for other setting values.
Due to the fact that this suppression filter influences control dynamics, ascertainment of control parameters by means of self-tuning or manual optimization has to be performed while oscillation suppression is active.
GMC-I Messtechnik GmbH R2500–23
GMC-I Messtechnik GmbH R2500–24

Adaptive Measured Value Correction

If a control loop is interfered with by periodic disturbance of the actual value, control can be improved by activating adaptive measured value correction. Periodic disturbance is thus suppressed, without impairing the controller’s ability to react to system deviations. Correction is adapted to the oscillation amplitude of the disturbance to this end, and only the mean value is forwarded to the controller.
Adaptation of correction to the disturbance is matched to prevailing control dynamics and requires no further parameters.
Prerequisites for improved control: – The oscillation amplitude of the disturbance must be constant, or may only change slowly. – The oscillation period must be less that half of the system’s delay time (parameter tu).
Due to the fact that correction greatly influences actual value ascertainment, control may also be worsened, for example if: – Measured value deviations are irregular – Individual measured value outliers occur – Fluctuation is not periodic – The disturbance is noise-like

Hot-Runner Control

By configuring the switching output for heating as a hot runner (Outx = Hotr), the manipulated variable is read out as a rapidly pulsating signal, i.e. actuation cycle time is 0.1 seconds regardless of the actuation cycle time parameter setting. With the help of this configuration, the start-up circuit and boost functions are also enabled.
Start-Up Circuit
The start-up circuit is enabled with the StUP = YES configuration, or by means of the binary input when it has been configured as follows: In1 = StUP. The start-up circuit is only enabled for controller type PDPI. No start-up occurs for other controller types. The start-up procedure is initiated if the actual value is more than 2 °C less than the start-up setpoint after auxiliary voltage is turned on (reset)
or after the off state has been ended, or if the actual value drops to more than 40 °C less than the start-up setpoint after a start-up procedure has been completed or during dwell time.
Start-up continues until the actual value exceeds the start-up value minus 2 °C.
Dwell time then begins, which is selected with the dwell time parameter.
The actuation procedure is ended as soon as dwell time has expired.
If the currently valid setpoint is still so far beneath the start-up setpoint that the condition for ending actuation cannot be fulfilled, the start-up procedure continues indefinitely. In this case, control variable limiting by means of maximum manipulating factor would be advisable.
GMC-I Messtechnik GmbH R2500–25
The control variable is limited to the start-up manipulating factor.
The controller regulates temperature to the actuation setpoint.
The controller then regulates temperature to the valid setpoint.
GMC-I Messtechnik GmbH R2500–26
Temporary Setpoint Increase (boosting)
Temporarily increasing the setpoint in the hot-runner control mode can be used to free clogged mold nozzles of “frozen” material remnants. This procedure is triggered by bit 3 of the controller function, which is set via the interface, keyboard or the binary input. The binary input must be con­figured as follows to this end: In1 = booS. If the binary input is not used to this end, setpoint increase is activated or stopped by simultaneosly pressing and holding the keys . Boosting is ended by clearing this bit, or is stopped automatically after maximum boosting time has elapsed. The relative increase is saved to the setpoint increase parameter, and the maximum duration of the increase is saved to the boost time parameter. The increase effects the setpoint or setpoint 2 only, and has no influence on the start-up setpoint or the ramp function. The setpoint value, and not the increase, is indicated with a b in the left digit.

Feed-Forward Control

When configured as a discontinuous or continuous-action controller (not as a step-action controller) control quality can be significantly improved by means of feed-forward control where abrupt load fluctuations prevail, if the binary input is configured for feed-forward control (In 1 = FEFO).
– When the contact at the binary input is closed, the controller’s manipulating factor is increased by an amount of Y FF, – and is reduced by the same value when the contact is opened. – No function during self-tuning.
Example: If a machine requires an average of 70% heating power during production operation, but only 10% during idle time, the difference of Y FF is set to 60%, and the binary input is only activated during production.

Program Controller

Activation At the configuration level with ProG = EnA
Function The current setpoint is determined exclusively by the program.
Program Each of the twelve program segments is defined by means of segment duration, targeted setpoint and the control tracks,
Sequence StoP The program has been completed or stopped, or hasn’t yet been started (after a reset).
GMC-I Messtechnik GmbH R2500–29
Eight programs with twelve segments each are saved to the controller and can be selected. The functions which otherwise influence the setpoint, such as setpoint swapping and setpoint ramps, as well as the start-up circuit and boosting for hot-runner control, are without function.
and the program can be set to end upon completion of the first through the eleventh segment as well.
The controller and the actuator outputs are inactive, relative limit value errors are suppressed. The momentary setpoint is set to the actual value. The program is started over again after it has been stopped.
run.X The program has been started, possibly automatically after a reset (X stands for the current segment).
The controller and the actuator outputs are active, relative limit value errors are enabled. Segment 1 is always executed when the program is started, and the initial setpoint is the actual value. The program can be started and stopped with a binary input: In1 = Prun.
Wt.X Same as for run.X.
If “wait until setpoint is reached” has been selected (with WAit = YES), the program waits until system deviation amounts to only 2° C before activating the next segment.
GMC-I Messtechnik GmbH R2500–30
hLt.X The running program has been halted, the momentary setpoint has been frozen (X stands for the current segment).
The program can be halted with a binary input: In1 = PhLt.
Control tracks Two control tracks can be activated for the duration of the segments. They can be assigned to available switching outputs with
the setting: Out... = tr... The states run and hLt can also be assigned to available switching outputs with the settings: Out... = Prun and Out... = PhLt.
Control parameters When the program controller is active, the control parameters should not (cannot) be set manually or by means of
self-tuning, because a constant setpoint is required for usable optimization results. Select ProG = diS to this end.
Display The displays are supplemented as follows at the operating level:
Operation The sequence can be controlled in the status display with the help of the up and down scroll keys, if it has not been configured
The momentary setpoint appears at the setpoint display when a program is running, and only dashes appear after the program has been ended because there is no longer an active setpoint. The setpoint cannot be changed. A status display also appears. Current status, namely StoP, run.X, Wt.X or hLt.X (X stands for the current segment), appears at the bottom display.

Manual Optimization

Parameters Pb I, Pb II, tu and tc are determined by means of manual optimization in order to maintain optimized controller dynamics. A start-up test or an oscillation test is performed to this end.
Preparation
Complete configuration (page 14) and parameter settings (page 27) must first be performed for use of the controller. – Deactivate the program controller, because a constant setpoint is required for the optimization procedure. – The actuators should be deactivated with the Off or Manual Operation function (page 13). –A recorder must be connected to the sensor and adjusted appropriately to prevailing circuit dynamics and the setpoint. – For 3-step or split range controllers, on and off time of the switching output for heating or the continuous output must be recorded (e.g. with an
additional recorder channel or a stopwatch).
– Configure limit transducer (Cout = OnOF). – Set read-out cycle time to the minimum value: tc = 0.1. – If possible, deactivate manipulating factor limiting: YH = 100. – Reduce (or increase) the setpoint so that overshooting and undershooting do not cause any impermissible values.
Performing the Start-Up Test
– dbnd = MRS Setting for 3-step and split range controllers (switching output for cooling may not be triggered)
dbnd = 0 Setting for step-action controllers (switching output for cooling must be triggered)
– Start the recorder. – Activate the actuators with Automatic Operation. – Record two overshoots and two undershoots. Actuation test is now complete for 2-step, continuous-action and step-action
controllers. Continue as follows for 3-step and split range controllers:
–Set dbnd to 0 in order to cause further overshooting with active switching output for cooling. Record two overshoots and two undershoots. – Record on-time T

If a start-up test is not possible, for example if neighboring control loops influence the actual value too greatly, if the switching output for cooling must be active in order to maintain the actual value (cooling operating point), or if optimization is required directly to the setpoint for any given reason, control parame­ters can be determined by means of sustained oscillation. However, calculated values for
tu
may be very inaccurate in this case under certain circumstances.
– Preparation as above. Test can be performed without a recorder if actual value is observed at the display, and if times are measured with a stopwatch. – dbnd = 0 Setting for 3-step, split range and step-action controllers – Activate the actuators with Automatic Operation, and if applicable start the recorder. Record several oscillations until they become uniform in size. – Measure oscillation amplitude x – Record on-time T
and off-time TII for the oscillations at the switching output for heating or the continuous output.

The value for tu is very inaccurate in this case. It should be optimized in the closed loop control mode.
Closed Loop Control Mode
The closed loop control mode is started after self-tuning has been completed: – Configure the desired control algorithm with controller type (Cout). – Adjust the setpoint to the required value. – For 3-step, split range and step-action controllers, the dead band can be increased from dbnd = 0, if control of the switching outputs (or continuous
output) changes too rapidly, for example due to an unsteady actual value.

Self-tuning is used to optimize controller dynamics, i.e. the Pb I, Pb II, tu and tc parameters are set.
Preparation
– Complete configuration must be performed before – The setpoint value is adjusted to the value which is required after – Deactivate the program controller.
Start
– Self-tuning can only be started if it has been enabled (configuration: tunE = EnA). – Briefly pressing both keys simultaneously at the operating level triggers self-tuning. Self-tuning cannot be
started in the “actuator” or “limit transducer” mode.
tun1...tun9 blinks at the display at all levels during self-tuning. – The controller is switched to the automatic operating mode after self-tuning has been successfully completed.
– In the case of 3-step controllers, cooling is activated if the upper limit value is exceeded in order to prevent overheating. Self-tuning then performs an oscillation
test around the setpoint.
Sequence
– The setpoint which is active when tuning is started remains valid and can no longer be changed. – Activation or deactivation of setpoint 2 does not
become effective. – Selected setpoint ramps are not taken into consideration. – If started at the operating point (actual value approximates the setpoint value), overshooting cannot be avoided. – There are no time limitations for the sequence. Self-tuning may take quite a long time, depending upon the control system.
Abort
– Self-tuning can be aborted at any time with the key ( automatic operating mode), or by switching off with the key. – If an error occurs during self-tuning, the controller no longer reads out an actuating signal. In this case, self-tuning must be aborted with the
key. Additional information regarding error messages upon request.
Self-tuning is enabled upon shipment from the factory (default setting). Starting the self-tuning function can be disabled in the configuration.

Limiter

If a controller needs to be deactivated in the event of a limit value violation within the control loop, the controller must be configured as a limiter ( The limiter can be combined with all controller types. – The limiter responds to the second limit value, which must be set and configured accordingly. – The controller is deactivated as soon as a second limit value is violated. The controller becomes active again when there are no more limit value errors. – If the controller is to remain continuously deactivated after limit value monitoring has been triggered, the alarm memory must be activated
(configuration: AL2 = Stor).
– The limit value errors must then be cleared in order to reactivate the controller. This is accomplished by pressing the key and acknowledging
the Quit AL display within 5 seconds with the key.
– These errors can also be cleared with the binary input, if it has been configured to clear limit value errors (In 1 = quit).

Heating Circuit Monitoring

– Function – Can be set to active or inactive with the LbA configuration
– Without external transformer, without additional parameters – Assumes correct optimization of tu and Pb I control parameters!
Due to the fact that self-tuning generates other results in certain cases when heating circuit monitoring is activated, heating circuit monitoring must be activated before self-tuning is started.
– In the event of manual optimization or subsequent adaptation of control parameters, the lower limit for the tu parameter
must be observed:
Minimum tu =

Δt = maximum temperature rise during start-up
– Error message LE appears after approximately 2 times tu, if heat remains on at 100% and measured temperature rise is

Alarm History

• The alarm history includes 100 error status entries with the respective time stamps. Whenever at least one entire bit of the overall error status
changes, the complete error status is saved with the current time stamp.
• Recording is started over each time the device is reset, and data are lost if auxiliary power fails. Recording can be activated with the setting
HISt = YES in the configuration, or via interfaces.
• After the ring buffer has been filled to capacity with 100 entries, the oldest entry is deleted each time a new one is recorded.
• Entries can only be read out via the bus interface or the infrared interface. See the interface description for detailed information.

Data Logger

• The data logger has enough capacity for 3600 sampled value pairs including actual values and manipulated variables. The logger sampling cycle
can be configured within a range of 0.1 to 300.0 seconds. This results in recording times of 0.1 to 300 hours (6 minutes to 12 days).
• Recording must be started over again each time the device is reset, and data are lost if auxiliary power fails.
• Recording can be started via a binary input, with the setting LoGG = YES in the configuration or via interface.
• After the ring buffer has been filled to capacity with 3600 entries, the oldest values are deleted as new ones are recorded.
• Entries can only be read out via the bus interface or the infrared interface. See the interface description for detailed information.

Attention!
!
Replacement with regard to features B and C:
• Features B1 and B2 are identical for both devices.
• Features C1 and C2 for the R2400 are feature C1 for the R2500.
• Feature C3 cannot be replaced with the R2400.
• Feature C4 for the R2400 is feature C2 for the R2500.
The following functions cannot be replaced:
• Position acknowledgement display for step-action controller (R2400, feature A4). Step-action controller function is available.
• 24 V AC auxiliary power (R2400, feature C3)
The following rewiring is required:
• The connector terminals on the R2400 can still be used, because the pin assignments are identical except for a few exceptions. The two plug connectors can be pulled out after loosening the lacquered screws.
• In the case of 230 V AC auxiliary power (R2400, feature C1), the conductor connected to terminal 13 is moved to terminal 12.
• If the actuating signal for cooling is read out via the relay, the corre­sponding connection must be changed (see table on page 47).
• If both actuating signals are read out via relay, the relay connections must be changed (see table on page 47).
Converting Parameters
In the case of the R2500, the proportional bands are specified in the unit of measure of the controlled variable, instead of as a percentage of the
measuring range span as is the case with the R2400. Conversion is accomplished as follows: Pb (R2500) = Pb (R2400) x mrs (R2400) / 100%.
