Safety features and safety precautions
The R2600 / R2601 controller is constructed and tested in compliance with the safety rules of IEC 1010-1 / VDE 0411-1.
When properly used, the safety of both the user and the unit is assured.
Read the operating instructions carefully and completely beforeyou use your unit. Follow them in all respects.
Make the operating instructions accessible to all users.
Please note the following safety precautions:
– The controller must only be connected to a line corresponding to the nominal range of use (see connection diagram and nameplate) which is fused
for a maximum nominal current of 16 A.
– A switch or a power switch must be provided in the installation as isolating device.
The controller must not be used:
– When the exterior shows obvious signs of damage
– When it no longer functions correctly
– After prolongedstorage under adverse conditions(e.g. moisture, dust, temperature).
In such cases, take the controller out of service and secure it against accidental use.

Physical installation / Getting started
Bild 2, Case dimensions and panel cutout
The R2600 / R2601 is meant for panel installation. As far as possible, the mounting
site should be free from vibrations. Aggressive vapors reduce the service life of the
controller. Observe the VDE 0100 specifications when performing any work. Workon
the controller must only be performed by a qualified person who is familiar with the
danger involved.
From the front, insert the case into the cutout and from the rear, fasten it at the top
and bottom with the two screw clamps supplied. The typical starting torque is
10 Ncm and should not exceed 20 Ncm.
Side-by-side mounting of several units is possible without intermediate bars. The
supplied seals for maintaining protection class IP54 cannot be used in this case.
Protection class IP54 is only assured in the case of a sunk rotary button.
When installing one or more units, it is a general requirement to provide for unob-
structed air circulation. The ambienttemperature below the unitsmustnor exceed
50 °C.
Withdrawing the instrument module (e.g. for setting of theDIP switch):
– Hold the instrument module on the front at tray and diaphragm between thumb and
forefinger (the pressure exerted on the diaphragm unlocks the plug-in module)
– Pull strongly

Operation
Setting of values with the rotary knob
– Slight turning does not change the value to be set at first (medium range of the rotating angle) to avoid an accidental change.
– When turning stronger to the left or right against the spring tension, the value is decremented or incremented for coarse setting the faster the knob
is turned further (spring range).
– When the rotary knob is released, the spring range is left.
– After a change of the value in the spring range, vernier setting by approximately 5 digits is possible onthe medium range.
– The value is stored and effective after 2.5 s or after a key stroke. This is signalled by a brief blanking of the display.

OPERATING LEVEL CONTINUOUS AND STEP CONTROLLER
–Alarm function and error signalling sameas with automaticmode.
–The positioning outputsare not controlled by the controller function but by the
rotary knob.
–Manual/automatic switch-over is bumpless in both directions.
–Continuous controller: Theregulation ratio is shown in %. Changes in value are
slow in the spring ranges of the rotary knob and are
instantly passed to the control outputs.
–Step controller: The switching output I (more) / II (less) is directly control-
led by turning the knob to the right/left into the spring
range. With position readback available (marking A4), the
measured position is shown in % while lines are shown
with marking A2, A3.

–No alarm function
–No error signalling –The positioning outputs are inactive with the rotary knob not actuated. –The switching output I ("heat") / II ("cool") is directly controlled by
turning the knob to the right / left into the spring range

GOSSEN-METRAWATT GMBH 19
Manual mode with binary input 2
The controller can be switched to manual operation with binary input 2.
This is distinguished from the Off / manual mode with the key.
–Bumpless change-over to manual mode for all controller types.
–The last regulation ratio is „frozen“also on switching controllers.
–With limit monitor, the last switching state is maintained.
–Operation and display are the same as in automatic mode with the exception that the LED lights and the regulation ratio in the display can be
changed with the rotary knob.
–Parameter Y St must beset to0 during configuration as a discontinuous or a continuous action controller (controller types 2 through 5).
Feedforward control with binary input 2
During configuration as a discontinuous or a continuous action controller (controller types 2 through 5), control quality can be markedlyimproved by
means of feedforward control if large, sudden load changes occur.
–When the contact at binary input 2 is closed, the extent of regulation provided by the controller is increased by value Y St.
–If the contact is opened, this value is reduced by the same amount again.
–No function when self-optimization is activated
–If Y St is set to 0, binary input 2 activates manual operation, (see above).
Example: If a heating unit in a machine needs to be run at an average of 70% power during production, but only at 10% during idle-time, differential
value Y ST is set to 60%, and binary input 2 is only activated during production.
