Installation
Instructions for use
•
Connection leads to the limit switch are to be routed separately from
the main current cables, e.g. cables to the electric motors or solenoids,
as otherwise inductive voltage peaks can reach the limit switch via the
power supply network, and damage them in spite of the integrated safety
circuit.
• Suitable DC supply is necessary as power supply to the limit switch. The
residual waviness of the feed voltage must not exceed max. 10%.
• Switch-off voltage peaks when switching inductive loads are to be de
-
creased using corresponding safety circuits, e.g. recovery diodes.
• An integrated overload safety circuit interrupts the switching function of
the limit switch in the case of overload. The limit switch is then automati
-
cally ready again after the duration of the overload state.
• The limit switch may not be installed in the vicinity of AC-operated con
-
sumers, e.g. AC solenoids, as otherwise malfunctions can occur. In any
case, a minimum clearance of 0.1 m must be observed.
• Only operation within the stated technical data is allowed.
• Connections must be made according to the connections diagram.
This switch is dedicated for the supervising of ONE trip point. When the
trip point is reached, the output A (pin 4) is non conducting, this means
a NORMALLY CLOSED function. Simultaneously the output B (pin 2)
becomes conducting, this means a NORMALLY OPEN function.
This switch is dedicated for the supervising of the neutral position of a
vale spool and is equipped with two trip points, operated by a movement
from within the neutral position. In this case the output A (pin 4) beco-
mes non conducting, this means a NORMALLY CLOSED function. If
the movement from the neutral position goes in the opposite direction,
the output B (pin 2) is non conducting, this means also a NORMALLY
CLOSED function.
