PSEN ml b 1.1 INFORMATION This gives advice on applications and provides information on special features. Safety Intended use The safety gate system is used for guard locking and interlocking swing gates and sliding gates. The safety gate system prevents the safety gate from being unlocked while there is any hazard within the danger zone (conditional unlock).
PSEN ml b 1.1 Safety regulations Safety assessment Before using a unit it is necessary to perform a safety assessment in accordance with the Machinery Directive. Functional safety is guaranteed for the product as a single component. However, this does not guarantee the functional safety of the overall plant/machine.
PSEN ml b 1.1 For your safety WARNING! Loss of safety function due to substituting an actuator from the interlocking and guard locking system Substituting an actuator for an inappropriate actuator may lead to serious injury and death. – You should prevent the interlocking and guard locking system from being manipulated with an inappropriate actuator. – Keep the substitute actuator in a safe place and protect it from unauthorised access.
PSEN ml b 1.1 Function description The interlocking and guard locking system prevents the safety gates to the danger zone from being opened while there is any hazard within the danger zone (machine movement, voltage, ...). The safety outputs may have a high or low signal, depending on the position of the actuator and the signal path of safety inputs S31 and S41 (solenoid operation).

INFORMATION If guard locking is deactivated using the auxiliary release, there is a low signal at safety outputs 12 and 22. An error code will be issued (see under Operation [ 27]) and the safety switch switches to a fault condition.
PSEN ml b 1.1 [2] [1] Legend [1] Auxiliary release screw Torx T10 [2] Security screw Torx T10, sealed with varnish when delivered Mode of operation: 1. Remove the security screw [2] using a Torx T10 screwdriver. 2. Rotate the auxiliary release screw [1] half a turn anti-clockwise using a Torx T10 screwdriver. The guard locking pin is displaced and the bolt is released. The safety gate to the danger zone can be opened. Recommissioning Recommission PSEN ml b 1.1 1.
PSEN ml b 1.1 Prevent restart To prevent the machine restarting (unintentionally) while there is someone inside the danger zone, a padlock can be attached via the through hole on the actuator (see diagram). As a result the actuator cannot engage with the safety switch, guard locking is not activated and the machine is prevented from starting.
PSEN ml b 1.1 PIN Function Terminal designation Cable colour (Pilz cable) 6 Operation of solenoid to open and close guard locking (channel 1) S31 Pink 7 0 V UB A2 Blue 8 Reserved Y1 Red NOTICE The colour marking for the connection lead only applies for the cable that Pilz supplies as an accessory EMC requirements } Ensure the wiring and EMC requirements of IEC 60204-1 are met. } The power supply must meet the regulations for extra low voltages with protective separation (SELV, PELV).
PSEN ml b 1.1 WARNING! Potential loss of safety function due to failure to test for a safe condition Depending on the application, serious injury or death may result. – Use an evaluation device/safety system to test whether the plant is in a safe condition. – Do not operate the solenoid of the PSEN ml b 1.1 via S31/S41 unless the plant is in a safe condition. } Use in PL e (Cat.
