Function Description
The control module PNOZ pe1p, in conjunction with the expansion modules, is used to ex-
pand a safety circuit. It is driven from a master controller (e.g. safe outputs on a PSS).
When operating voltage is supplied the "POWER" LED will light.
}24 V DC are available at the terminals K1-Y3 and K2-Y4 (e.g. the PSS output has a high
signal):
– The LEDs "K1" and "K2" are lit.
– At the expansion module control output connected to the PNOZpower bus there is a
high signal. The unit is active.
}0 V DC are available at the terminals K1-Y3 and K2-Y4 (e.g. the PSS output has a low
signal):
– The LEDs "K1" and "K2" go out.
– At the expansion module control output connected to the PNOZpower bus there is a
low signal.
NOTICE
When controlling an expansion module via the den PNOZpower bus the
switch-on delay/delay-on de-energisation of the controlling device (e.g base
unit, control module, ...) and the expansion module are added together.
Operating modes
}Single-channel operation: No redundancy in the input circuit, earth faults in the input cir-
cuit are detected.
}Dual-channel operation with detection of shorts across contacts: Redundant input circuit,
detects PNOZ pe1p
– earth faults in the input circuit,
– shorts across contacts in the input circuit.
NOTICE
When semiconductor outputs are used, the detection of shorts across con-
tacts will depend on the master controller.

Installation
}The unit should be installed in a control cabinet with a protection type of at least IP54.
}Use the notches on the rear of the unit to attach it to a DIN rail.
}Fit the unit to a horizontal DIN rail. If other mounting positions are used, the switching
capability values stated in the technical details cannot be maintained.
}There are 2 sockets on the rear of the PNOZ pe1p.
The base unit/control module and the expansion modules are connected using the jump-
ers supplied.
NOTICE
Always connect a terminator to the first and last device.
}Only use terminators, jumpers and terminals of the modular safety system PNOZpower.
}Layout:
– The control module and the expansion modules can be installed in any position on
the PNOZpower modular safety system.
}Maximum hardware:
– 1 control module
– 4 expansion modules
– 1 power supply unit

WARNING!
Risk of electrocution!
When voltage is applied, contact with live components could result in seri-
ous or even fatal injury from an electric shock.
The plug-in connection terminals should only be connected and disconnec-
ted when the voltage is switched off.

Wiring
Please note:
}Information given in the "Technical details [ 13]" must be followed.
}Calculation of the max. cable length lmax in the input circuit:
Rlmax
Rl / km
Imax =
Rlmax = max. overall cable resistance (see Technical details [ 13])
Rl/km = cable resistance/km
}When driven via semiconductor outputs, the maximum cable runs will depend on the
master controller.
}Use copper wiring with a temperature stability of 60/75 °C.
}To prevent EMC interferences (particularly common-mode interferences) the measures
described in EN60204-1 must be executed. This includes the separate routing of cables
of the control circuits (input, start and feedback loop) from other cables for energy trans-
mission or the shielding of cables, for example.
}The control module and the input circuits must always be supplied by a single power sup-
ply.
}Use the power supply PNOZ pps1p or an external power supply that complies with the
regulations for extra low voltages with safe electrical separation (SELV, PELV).

Operation
NOTICE
The safety function should be checked after initial commissioning and each
time the plant/machine is changed. The safety functions may only be
checked by qualified personnel.
Status indicators
LEDs indicate the status and errors during operation:

Supply voltage is present.
K1
Channel 1 input circuit is closed.
K2
Channel 2 input circuit is closed.
FAULT
Internal error, wiring error or short across contacts
NOTICE
The electronic fuse and "FAULT" LED only work when terminal S11 is con-
nected. Only then can the PNOZ pe1p detect shorts across contacts. If ter-
minal S11 is not connected, the master controller must monitor for shorts
across contacts.

Faults – Interference
By closing or interrupting the input circuit you can check whether the unit switches on or off
correctly.
For safety reasons, the control module cannot be started if the following faults are present:
}Contact malfunction: As the expansion module is connected to a base unit or a control
module, reactivation will not be possible if the contacts have welded after the input circuit
has opened.
}Open circuit, short circuit or earth fault ( e.g. in the input circuit)
