Wiring the Inputs and Outputs
7-18 Operating Manual: PSS 3075-3 Series
Single-pole outputs
Features:
• 18 single-pole outputs O/T2.0 ... O/T2.3, O2.8 ... O2.15, O4.0 ... O4.2
and O4.8 ... O4.10.
The 4 outputs O/T2.0 ... OT2.3 can be configured together as test pulse
outputs.
• Output current: 1.5 A
• The continuous current over all the outputs must not exceed the following
values:
- max. total of 10 A at terminals X1 and X2
- max. total of 10 A at terminals X8 and X9
• The test pulse outputs are push-pull outputs. Do not use the push-pull
level to drive a load to L+, otherwise the switch-off test will detect a
connection to L+ and will register an error.
• Do not connect two adjacent inputs to the same test pulse.
• The four test pulse outputs can only be configured together as test pulse
outputs or as single-pole outputs that do not use test pulses (see
Programming Manual). Configuration will be automatic, depending on the
number of test pulse outputs used:
Number < 4: O/T2.0 ... O/T2.3 are test pulse outputs
Number = 0: O/T2.0 ... O/T2.3 are single-pole outputs
• If only one test pulse is used, the remaining test pulse outputs must
remain unconnected.
• Each output is protected against short-circuit, overload and excess
temperature. Outputs are designed for resistive and inductive loads.
• All outputs have a common second shutdown route. This means that the
programmable safety system can be used in single-channel operation for
applications up to category 3 in accordance with EN 954-1 (11/94).
Please note that the second shutdown route is only tested when the
safety system switches from STOP to RUN and that a feedback loop
must be used with single-channel operation.
To achieve category 4, two actuators must be connected in series to two
different outputs.
