operation may cause severe personal injury and extensive damage to property!
Important: This unit is not a safety temperature limiter to DIN EN 60730-1!
The unit must not be installed in potentially explosive atmospheres. If a process function originating
from an explosion-risk area is to be processed by the unit, which is installed outside the explosion-
risk area, all supply lines of the unit leading into the explosion-risk area must be installed using
approved safety barriers!
Error-free and safe operation of the unit requires its careful transportation and storage, as well as
correct assembly and installation. This unit may only be installed, configured, parameterised and
commissioned by qualified persons who are familiar with the installation, commissioning and
maintenance of comparable devices and with the system in which the unit will be used and who have
appropriate knowledge in the field of instrumentation and control. Operating staff of the system in
which the unit is to be used must be instructed by suitably qualified persons on operation and
control of the unit.
Please observe and comply with:
•The contents of the present manual regarding installation and operation of the unit, in

1.2 Instructions for installation
Please read the installation instructions carefully and comply with all points mentioned in them when
installing the unit. Non-compliance with these instructions for installation may result in faults or
malfunctions or the unit may fail to comply with the required EMC guidelines and thus the conditions
for CE-conformity will not be fulfilled.
Before connecting the unit and putting it into operation, please ensure that the operating voltage
and the conditions for the operating voltage required by the unit correspond to the conditions on
site (see name plate and technical data). If required, take any appropriate measures.
Please ensure that the control and load voltage on site are switched off and secured against
accidental reactivation during installation of the unit. The electrical connections must be in
accordance with relevant national rules and regulations. The supply lines for the device must be
installed such that they are free from any tensile loads and are not exposed to risks of shearing or
crushing under any circumstances.
The mains connection and the connections for consumers must each be provided by suitable cables
with a cross-section of at least 1.5 mm².
For sensor lines and signal lines, the use of shielded cables is strongly recommended (especially if
lines are long and/or running along potential sources of interference); for thermocouples, shielded
compensation lines should also be used. Sensor lines and signal lines should be installed such that
they are spatially separated from the load and control lines (high-voltage lines). If signs of incorrect
switching behaviour are detected, the system must be put out of operation until the cause is
eliminated.
Normal terminals may not be used for intermediate clamping of compensation lines for
thermocouples since this would result in the creation of additional thermocouples that could falsify
the measurements.
The controller is designed for the switching of ohmic heating units. Any inductive loads activated by
the unit, such as contactors, valves, motors, transformers, etc. must be wired separately and
provided with unit-specific suppression devices.
When connected to the "Line 10A Fuse int." terminal or type W-720 / W-730, the load circuit is
protected against overcurrent with an internal 5x20mm 10AT fine-wire fuse. When connected to the
"Line unfused" terminal, the load circuit must be protected against overcurrent with a suitable fuse
by the customer.
The present manual does not contain an exhaustive list of all regulations, standards, etc. that must
be observed and complied with when using the unit in combination with other systems and plant.
Any such regulations, standards, etc. shall be complied with and observed by the operator of the unit
with regard to the specific application.

2General information
The W-700 temperature controller series offers a wide range of features, intuitive functions and an
extremely long service life. The FAT (fast adaptive tuning) algorithm continually adjusts to the control
loop thus ensuring precise control. The setting of PID parameters and the execution of an autotuning
procedure are not required. All functions can be quickly accessed and changed in the plain-text
menu. The integrated hybrid relay system ensures a long service life with low losses in the controller.
The additionally installed cut-off relay minimises the risk of damage should the hybrid relay fail. The
self-optimising FAT control algorithm makes sure that the target temperature is reached quickly
while avoiding overshoots. The two independent universal sensor inputs allow easy connection of a
variety of common resistance temperature sensors as well as thermocouples. The limiter module
provides additional protection and flexibility in the control strategy. The electronics are protected
against overcurrent and overheating.
The multi-colour LED provides highly visible, simple signalling of the various operating modes.
3Putting into operation
The unit comes supplied with standard parameters. This configuration matches the specific
requirements in very few cases. This means that the unit must be adjusted to the desired
temperature limits of the application and the type of sensor used.
3.1 Wiring
If the unit is supplied ready for connection with plug-in connectors, please ensure the correct pin
assignment of the connectors. All cables used must comply with the relevant current and voltage
requirements.
In the case of units for connection by the user, the front panel must be removed in order to access
the internal terminals. To do this, open the cover and remove the 4 Phillips screws (PH1). If
necessary, remove the front panel from the housing by gently shaking it or pushing the mains cable.
To begin wiring, place the front module next to the enclosure on a non-slip surface. Or if the
enclosure is already wall-mounted, the front module can be clamped under the spacer bolts.
All spring-loaded terminals can be easily activated using a flat-blade screwdriver. For a description of
the terminals, see section 13 Terminal assignment on page 21.
3.2 Switching on
Check the wiring again carefully!
Incorrect wiring of the unit can cause serious damage to the unit and the system! Make sure that the
load voltage of the system is switched off when you switch on the unit for the first time as the unit
has not yet been adjusted to the system and may under certain circumstances trigger malfunctions.
Now switch on the operating voltage of the unit.

5Schematic and mode of operation
The unit has two independent sensor inputs, each of which can be used for the control function
and/or limiting function. The control function tries to reach the set temperature quickly and to
maintain it. The limiting function monitors the temperature to see if it exceeds the limit temperature
and to shut down if this is the case. The output then controls heating or cooling.
