Installation version 1.0 2021
1) Configuration of the output modes:
Select the output mode, current (4–20 mA) (optional) or voltage (0–
10 V)
for each output (1-4) by installing jumpers as shown in Figure 4.
On a display version of the device, the output scale can be changed
via the configuration menu. An external configuration tool is avail
-
able for devices without user interface.
First, select the output mode by jumper, then select the output scale
(4–20 mA (optional) / 0–10 V / 2–10 V / 0–5 V) via the configuration
menu. Please see the user manual for more details.
The seller is obligated to provide a warranty of five years for the deliv
-
ered goods regarding material and manufacturing. The warranty period
is considered to start on the delivery date of the product. If a defect
in raw materials or a production flaw is found, the seller is obligated,
when the product is sent to the seller without delay or before expira
-
tion of the warranty, to amend the mistake at his/her discretion either
by repairing the defective product or by delivering free of charge to
the buyer a new flawless product and sending it to the buyer. Delivery
costs for the repair under warranty will be paid by the buyer and the
return costs by the seller. The warranty does not comprise damages
caused by accident, lightning, flood or other natural phenomenon, nor
-
mal wear and tear, improper or careless handling, abnormal use, over
-
loading, improper storage, incorrect care or reconstruction, or changes
and installation work not done by the seller. The selection of materi
-
als for devices prone to corrosion is the buyer’s responsibility, unless
otherwise is legally agreed upon. Should the manufacturer alter the
structure of the device, the seller is not obligated to make comparable
changes to devices already purchased. Appealing for warranty requires
that the buyer has correctly fulfilled his/her duties arisen from the de
-
livery and stated in the contract. The seller will give a new warranty for
goods that have been replaced or repaired within the warranty, how
-
ever only to the expiration of the original product’s warranty time. The
warranty includes the repair of a defective part or device, or if needed,
a new part or device, but not installation or exchange costs. Under no
circumstance is the seller liable for damages compensation for indirect
damage.
