Mechanical Installation / Preparation
The RXX0 controller is intended for installation to a control panel. The installation location should be vibration-free to the
greatest possible extent. Aggressive vapors
shorten the service life of the controller.
Requirements set forth in VDE 0100 must
be observed during the performance of all
work. Work on the device may only be carried out by trained personnel who are familiar with the dangers involved.
Set the housing into the panel cutout from
the front, and secure it from behind at the
left and right-hand sides with the two included screw clamps.
Push the screw clamps first all the way up
to the limit stop in direction 1 and subsequently in direction 2 for this purpose.
Typical tightening torque amounts to
10 Ncm, and a value of 20 Ncm should not
be exceeded.
In general, unobstructed air circulation
must be assured when one or several devices are installed. The ambient temperature underneath the devices may not exceed 50 °C.

Differences between R2080/R2100/R2180 and GTR0208/GTR0210/GTR0218
Controllers R2080, R2100 and R2180 do not supersede analog devices GTR0208, GTR0210 and GTR0218 in
a fully compatible manner. Please note the following deviations:
Temperature sensor Pt100
As a rule, controllers R2080, R2100 and R2180 are provided with a 3-wire-connection.
Consequently, for Pt100 (but not in the case of a thermocouple), terminals 18-19 at controllers R2080 / R2100
or terminals 12-13 at controller R2180 must be shunted.
Sensor rupture protection
Controllers R2080, R2100 and R2180 are able to detect a broken sensor and/or polarity reversal of the sensor,
whereupon the actuating outputs are deactivated and an alarm is triggered at the same time.
If the actuating outputs are to assume a certain status, it must be set with parameter Y SE.
Protective conductor connection
According to EMC requirements controllers R2080, R2100 and R2180 must be provided with a protective conductor connection.
Cooling output
In the case of 3-step controllers R2080 / R2180, the 2
Limit contact
In the case of controller types R2080 / R2180 with limit contact, the configuration of the R2080 / R2180 must
be changed from CnF1 = 0xx0 to 0xx4 while using the break contact (reverse action principle). Switching point
distance ∆w can only be set as a relative MAX alarm to a value above zero for the R2080 / R2180.
Heating current display / monitoring
Heating current transformer GTY 2570 127 R0x can no longer be used in connection with R2080.
Instead, 3-input and/or 4-input current transformers GTZ 4121 must be fitted for acquiring heating current.
This offers the additional feature of not only indicating the heating current but also monitoring antivalence pro-
vided the R2080 has been appropriately set. In this case, an alarm is triggered if current is too low while heating
is activated or if current is not „off“ while heating is deactivated (see also page 30).
RC elements
In contrast to GTR0210, no RC elements for spark suppression have been fitted in controllers R2080, R2100
and R2180. It is therefore recommended retrofitting the controlled actuators (contactors, solenoid valves, etc.)
with the associated RC elements.

Adjusting Control Performance – Manual Self-Tuning
Parameters Pb 1, Pb 11, tu and tc are determined by means of manual self-tuning in order to maintain opti-
mized controller dynamics. An actuation test or an oscillation test is performed to this end.
Preparation
–Complete configuration (page 25) and parameters configuration (page 16) must first be entered for use of the
controller.
–The actuators should be deactivated with the off function (page 15).
–A recorder must be connected to the sensor and adjusted appropriately to prevailing circuit dynamics and
the setpoint.
–For 3-step controllers, on and off-time must be recorded for switching output I (e.g. with an additional
recorder channel or a stopwatch).
–Configure as limit transducer (controller sort = 0) (see page 25).
–Set read-out cycle time to the minimum value: tc = 0.5.
–Deactivate PWR limiting. YH = 100.
–Reduce (or increase) the setpoint so that overshooting and undershooting do not cause any impermissible
values.
Performing the Actuation Test
–dbnd = MRS Setting for 3-step controller (switching output II may not be triggered)
dbnd = 0Setting for step-action controllers (switching output II must be triggered)
–Start the recorder.
–Activate the actuators with automatic operation.
–Record two overshoots and two undershoots.
The actuation test is now complete for 2-step and step-action controllers.
Continue as follows for 3-step controllers:
–Set dbnd to 0 in order to cause further overshooting with active switching output II. Record two overshoots
and two undershoots.
Record on-time T
and off-time TII at switching output I or the continuous output for the last oscillation.

Evaluating the Actuation Test
–Apply a tangent to the curve at the intersection of the actual value and the setpoint, or at the cut-off point of
the output.
–Measure time ∆t.
–Measure oscillation amplitude x
MRS = Measuring range span of the configured sensor type (compare Configuration, see page 25), not the
measuring range according to C Designation
Performing the Oscillation Test
If an actuation test is not possible, for example if neighboring control loops influence the actual value too greatly,
if switching output II 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.
–Same preparation as for actuation test. The test can be performed without a recorder if the actual value is
observed at the display, and if times are measured with a stopwatch.
GOSSEN METRAWATT GMBH19
–dbnd = 0Setting for 3-step and step-action controllers
–Activate the actuators with automatic operation, and start the recorder if applicable. Record several
oscillations until they become uniform in size.
–Measure oscillation amplitude x
–Record on-time T
and off-time TII at switching output I for the oscillations.

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 sort.
–Adjust the setpoint to the required value.
–The dead band can be increased from dbnd = 0 for 3-step and step-action controllers if control of switching
output I and II changes too rapidly, for example due to an unsteady actual value.

water cooler. The actuating cycle is equal to tc.
A harmonic-free PDPI control algorithm regulates switching output I or II in order to increase
or decrease the actual value. The duration of the actuating impulse is equal to tc. The dead
band dbnd is symmetric to the setpoint.
Manual Operation with Binary Input
Switching to manual operation is possible via the binary input.
–Bumpless switching to manual operation with all controller sorts
–The last PWR is “frozen” for step-action controllers as well.
–The last switching status is retained for limit transducers.
–Operation and display are identical to automatic operation, except that the LED lights up and the PWR
can be changed in the PWR display with the and keys.
–When configured as a step-action controller (controller sort set to 2 through 5), the Y St parameter must be
set to 0.
–The “alarm 2” configuration digit must be set to a value of 8 ... F to this end (compare CnF2 on page 27)
PWR Out Offset with Binary Input
When configured as a step-action controller (controller sort set to 2 through 5), control quality can be
significantly improved by means of PWR out offset where abrupt load fluctuations prevail.
–When the contact at the binary input is closed, the controller’s PWR is increased by an amount equaling
YSt.
–It is reduced by the same value when the contact is opened.
–No function during self-tuning
–Where Y St = 0, the binary input activates manual operation (see above).
–The “alarm 2” configuration digit must be set to a value of 8 ... F to this end (see also CnF2 on page 27).
Example:
If a machine requires an average of 70% heating power during production operation, but only 10% during idle
time, the difference of Y ST is set to 60%, and the binary input is only activated during production.

Heating Current Monitoring
FunctionHeating current is acquired with an external transformer (e.g. GTZ 4121).
AMPS current
setpointHeater phase nominal current is entered for this parameter. AMPS can be set to Auto for
An alarm is triggered if the current setpoint is fallen short of by more than 20% with
activated heat (control output I active), or if current is not “off” when the heat is switched
off. The alarm is not triggered until heating current is high enough when output I is active,
or when current drops to zero when output I is inactive.
Monitoring is inactive if the controller is switched to oFF, as well as in the case of step-
action controllers.
automatic adjustment with the heater switched on. The currently measured value is
saved to memory.
Heating Circuit Monitoring
Function– Can be set to active or inactive with the “Alarm 1” configuration digit (see
“Configuration” ).
– Without external transformer, without additional parameters
– Requires correct optimization of tu and Pb 1 control parameters,
i.e. 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 value for the tu parameter must be observed:
minimum tu =
∆ϑ
⁄ Dt = maximum temperature rise during actuation
– Error message LE appears after approximately 2 times tu, if heat remains on at 100%
and measured temperature rise is too small.
– Monitoring is not active:
where controller sort = limit transducer, actuator or step-action controller
during self-tuning
with standard signal input (R2100 C30, C31)
where PWR limiting YH < 20%
