4.5 Electrical installation
Destruction of parts of equipment and loss of regulation control
`
All lines for connecting the magnetic sensor must be shielded.
`
Never wire or disconnect electrical connections while they are live.
`
Perform wiring work in the de-energized state only.
`
Use strands with suitable ferrules.
`
Wiring to the screen and ground (0 V) must be secured to a good
point. Ensure that the connection of the screen and earth is made to a
large surface area with a sound connection to minimise impedance.
`
Check all lines and plug connections before switching on the device.
`
Switch on operating voltage together with the downstream electronic
unit (e. g., control unit).
Basically, all connections are protected against external interference.
Choose a place of operation that excludes inductive or capacitive interfer-
ence influences on the magnetic sensor. When mounting the system keep a
maximum possible distance from lines loaded with interference. If neces-
sary, provide additional installations including screening shields or met-
allized housings. Contactor coils must be linked with spark suppression.
`
Pay attention to the maximum length of the connection cable between
sensor and downstream electronics.
`
Do not use tinned strands in connection with screw clamp connec-
tions.
In case of operating voltage 24 V DC and output circuit LD we recommend
use of terminal resistors ≥470 Ohm in order to avoid thermic overload.
With a 4-increment wide (= 360°) index/ reference signal, index/refer-
ence signal interpretation can be made after the 5th counting step (incre-
ment) only. Corresponding time delay has to be considered when power is
switched on.
Connection note acc. to RS422 standard
Please provide the channels with a 120 Ohm terminating resistor.
