5. Commissioning, operation
Option with relay
The relay parameters have to be set before voltage is
connected to the relay connections. This ensures human
safety against electric shock.
1. Setting the switch point
Place a jumper on the "switching threshold pins" (sw.p.).
■
Press the "push button" in order to select the switch point for the relay.
■
⇒ The selected value (m/s) will be shown on the display.
Store the jumper used, once the configuration is complete.
■
2. Setting the hysteresis
Place a jumper on the "hysteresis pins" (hyst.).
■
Press the "push button" in order to select the hysteresis for the relay.
■
⇒ The selected value (m/s) will be shown on the display.
Store the jumper used, once the configuration is complete.
■
Hysteresis
The hysteresis represents a dead band ≤ 20 % around the selected
range, which is anchored at the switch point (sw.p.) and extends around
it by the selected hysteresis range (hyst.).
