3.1 General instructions on installation
Warning
Undesired movement of the connected actuators and non−
defined switching states of the electronics can cause injury
to human beings or damage to property.
Before carrying out installation and/or maintenance work,
switch off the following in the sequence specified:
1. The compressed air supply
2. The following power supplies:
Ĉ the load voltage supply for field devices and proporĆ
tional directional control valves (plug X2, pin 1)
Ĉ the load voltage supply for the outputs (plug X6/X8,
pinĂ8)
Ĉ if applicable, the load voltage supply on the axis interĆ
face string
Ĉ the load voltage supply for the internal electronics of the
SPC200 and field devices (plug X2, pin 2).
Please note
Please note that the maximum permitted bus length
depends on the baud rate.
A bus segment is a bus cable which may contain up to 32
slaves (devices). The ends of the bus segment must be fitted
with a terminating resistor. Use plugs with an integrated terĆ
minating resistor if the SPC200 is installed at the end of a bus
segment.
