Pilz PSENme 3.2 User Manual

Installation and Operating Instructions

Plastic encased safety interlocking switch

Type

PSEN me2/PSEN me3

Intended use

The plastic encased safety switches PSEN me2 and PSEN me3 with separate actuator are suitable for the
mounting on safety guards. They are designated to trigger switching operations in control circuits.

Function

If the safety guard is opened the contact(s) with forced disconnection will break the safety control circuit (safety
contacts get opened).

Safety instructions

Improper installation or manipulation of the safety switch renders the personal protection function useless and can
cause serious injury or accidental death.

In order to maintain the maximum level of safety, always order and use actuators together with the correct safety switches.

protective cover

The protective cover must

be latched onto the actuator
after mounting. The protective cover prevents the
actuator from being easily dismantled and also provides
protection against overtravel of the actuator in case of
not proper installed mechanical end stops for the guard.

Mounting dimension for all actuators: 40 mm with M5- screws acc. DIN 912!

Installation

Installation by trained and qualified personnel only!

To mount the switch gear 2 screws M5 shall be used.

Actuator PSEN me2AS and PSEN me2AR:
The user shall make sure that the actuator is form-fit mounted. The actuator mounting should not be solvable with
simple tools. The mounting requires 2 screws M5 acc. DIN 912.
The switch and the actuator shall be aligned during installation in such a way that the maximum permitted
misalignment with closed safety guard, which is stated in the drawing, will not be exceeded. The actuator PSEN
me2AR has to be adjusted in such a way that the actuator can be inserted into the switch head without significant
lateral forces.

The mounting position is any desired but shall support inspection and replacement if necessary by qualified
personnel. Choose such a mounting position that no foreign parts seep into the opening of the actuating device.
The rated degree of protection (IP-Code) of the switch applies only with closed cover lid and when an at least evenly
matched cable gland with adequate cable is used.

The switches shall not be used as mechanical end stops.

Mounting M20/M16 cable gland/cable:

Connection type:
2 or 4 screw connectors M3,5 or
6 screw connectors M3
Conductor cross section:
single core 0,5-1,5 mm²/litz wire with
connector sleeve 0,5-1,5 mm²

After mounting the gland
remove the piece inside

Electrical connection

The electrical connection shall only be carried out by trained and qualified personnel!

The electrical contacts of the switches PSEN me2 and PSEN me2.1 feature 2 screw terminals M3,5.
Tightening torque M = 0,8 Nm.
The electrical contacts of the switches PSEN me3, PSEN me3.01, PSEN me3.02, PSEN me3.1 and PSEN me3.11
feature 4 screw terminals M3,5.
Tightening torque M = 0,8 Nm.
The electrical contacts of the switches PSEN me3.2 and PSEN me3.21 feature 6 screw terminals M3.
Tightening torque M = 0,6 Nm.

The connection requires a stranded wire with ferrule or a solid wire with a cross section of 0,5 – 1,5 mm².
For safety circuits acc. EN 60204 use the normally closed contact(s) (N.C.) only.

Installation and Operating Instructions

Start-up

Mechanical function test:
Actuate the safety guard und check the proper switching function.

Electrical function test in the safety control circuit:

- Opening the safety guard shall break off the energy of the drive.

- The drive shall only be energized when the safety guard is in its closed position.

Maintenance / Inspection

The switching device is maintenance-free. For trouble-free operation and a long service life the device should be
inspected regularly. Ensure that:

- all components are secure and tight

- switching functions operate properly

- all sealing gaskets are in proper condition

- the components show no signs of tear and wear.
If defects are detected the complete switching device and the actuator have to be replaced.

Liability disclaimer

By breach of the given instructions (concerning the intended use, the safety instructions, the installation and
connection through qualified personnel and the testing of the safety function) any liability expires.
