5 Description of Product
5.1 General Information
Walther Temperature Controller Bundles (WTRB) are available for all heating plates and heating hoses from
Walther Systemtechnik GmbH
. Based upon the selected heating technology product,
Table 2
is your reference
guide for choosing the matching temperature controller bundle; the individual bundle contains a suitable tem-
perature controller (WTR) and the adapted solid-state relay (WSSR). Please observe the following instructions
when using the Walther Temperature Controller Bundles (WTRB):
•
The device is not suitable for installing in explosion-prone areas.
•
Make sure that you follow the regulations of the DIN VDE 0100 "Construction of Low-Voltage Systems",
respectively the guiding state regulations (e.g. based upon the IEC 60364) when selecting the wiring
material, or during the installation, or for the electrical connection of the device.
•
For maximum load, the lines have to be heat-resistant up to 80 °C.
•
Only a trained and qualified technician will take care of the electrical connection.
•
The device was designed for installation in switch cabinets or systems. The customer fuse protection
must not exceed 20 A. For all service / repair work, the device has to be completely disconnected from
current.
•
Make sure that the load circuit will be protected for the maximum relay current; this will prevent a welding
of the output relay in case of a short circuit.
•
The electromagnetic compatibility is accordance with standards and regulations mentioned under
‘tech-
nical data‘.
•
Make sure that the lines for input, output and supply are physically separated and will not be laid paral-
lelly.
•
Lines for sensors and interfaces will be twisted and shielded. Do not carry out near current-carrying
components or lines. Make sure that the shielding is grounded on one side.
•
Do not connect other or additional users to the terminal plugs.
IMPORTANT
The WTR-x Temperature Controllers come with a standard configuration which matches most
of the heating elements of Walther Systemtechnik. The following chapters of this operating
manual refer to this standard configuration.
