4.15 Limit switch (SP1)
The pyrometer is equipped with a switch contact (opto relays; max. 50 V DC, 0.2 A; max. power
300 mW), controlled from the measuring signal. The contact is activated with:
Close above: The contact closes (switches to ground), if the temperature entered in the SP1
box is exceeded. If the temperature falls below that value minus the hysteresis the contact opens
(a hysteresis between 2 and 20 °C can be set to avoid oscillating of the switch in the switch
point).
Close below: The contact closes (switches to ground), if the temperature falls below the
entered value in the SP1 box. If the temperature exceeds that value plus the hysteresis the
contact opens (a hysteresis between 2 and 20 °C can be set to avoid oscillating of the switch in
the switch point).
