1. Switching point (display required)
• Install a jumper to pins labeled sw.p. (switching point).
(See Figure 5)
• Press down on the pushbuon to select the switching point (e.g.
5,05 m/s = NC) of the relay. The chosen value (m/s) is shown on the
display.
• Remove and store the jumper aer the conguraon is completed.
2. Hysteresis (display required)
• Install a jumper to pins labeled hyst. (hysteresis). (See Figure 5)
• Press down on the pushbuon to select the hysteresis of the relay
switching point. The chosen value (m/s) is shown on the display.
• Remove and store the jumper aer the conguraon is completed.
NOTE! Relay conguraon jumpers must be removed and stored for
proper operaon.

The seller is obligated to provide a warranty of ve 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 producon aw is found, the seller is obligated,
when the product is sent to the seller without delay or before expira-
on of the warranty, to amend the mistake at his/her discreon either
by repairing the defecve product or by delivering free of charge to
the buyer a new awless 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, ood or other natural phenomenon, nor-
mal wear and tear, improper or careless handling, abnormal use, over-
loading, improper storage, incorrect care or reconstrucon, or changes
and installaon work not done by the seller. The selecon of materials
for devices prone to corrosion is the buyer’s responsibility, unless other-
wise 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 fullled his/her dues arisen from the delivery and
stated in the contract. The seller will give a new warranty for goods
that have been replaced or repaired within the warranty, however only
to the expiraon of the original product’s warranty me. The warranty
includes the repair of a defecve part or device, or if needed, a new part
or device, but not installaon or exchange costs. Under no circumstance
is the seller liable for damages compensaon for indirect damage.
RECYCLING/DISPOSAL
The parts le over from installaon should be
recycled according to your local instrucons.
Decommissioned devices should be taken to a
recycling site that specializes in electronic waste.

WARRANTY POLICY
Hysteresis represents a dead-zone less than or equal to 20 % of the
range selected. The hysteresis is anchored at the switching point (sw.p.),
extending to the hysteresis range selected.

Dead
zone
In the above example switching point is set at 1,5 m/s, and hysteresis
is set at 0,25 m/s. As the velocity increases over 1,5 m/s, the relay
will open/close. As velocity reduces, the relay will not close/open
unl the velocity passes 1,25 m/s, thus prevenng rapid cycling.
