Mechanical Installation / Preparation
The RXX0 controller is intended for installa-
tion to a control panel. The installation lo-
cation 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 car-
ried out by trained personnel who are fa-
miliar 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 in-
cluded screw clamps.
Push the screw clamps first all the way up
to the limit stop in direction 1 and subse-
quently 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 de-
vices are installed. The ambient tempera-
ture underneath the devices may not ex-
ceed 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 con-
ductor connection.
Cooling output
In the case of 3-step controllers R2080 / R2180, the 2nd switching point cannot be used as an NC contact.
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.

Actuation suppression: Alarm suppression remains inactive during actuation (configuration digit “alarms 1 and 2”)
until temperature has exceeded the lower limit value for the first time. During cooling, suppression is active until
temperature has fallen below the upper limit value for the first time. Suppression is active when auxiliary power
is activated, if the current setpoint is changed or setpoint 2 is activated, or if switching takes place from off to

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).
–Arecorder 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:
–Setdbnd to 0in order to cause further overshooting with active switching output II. Record two overshoots
and two undershoots.
Record on-time TIand off-time TII at switching output I or the continuous output for the last oscillation.

GOSSEN METRAWATT GMBH 19
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 xss, or overshooting for step-action controllers ∆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 optimiza-
tion 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 cir-
cumstances.
– 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.

– Activate the actuators with automatic operation, and start the recorder if applicable. Record several
oscillations until they become uniform in size.
–Measureoscillation amplitude xss.
–Recordon-time TIand off-time TII at switching output I for the oscillations.
Evaluating the Oscillation Test
1) If either TIor TII is significantly greater than the other, value tu is too large.
Correction for step-action controllers in the event that TIor TII is smaller than tY:
tY •tY tY •tY
Multiply Pb 1 by , if TIis smaller, or by , if TII is smaller.
TI•TITII •TII
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.
–Adjustthesetpoint 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.
