Section4 Check and debugging
Make sure to test the operation of BLPS after installation to verify that BLPS operates as
intended. Make sure to stop the machine until the test is complete. Unintended function
settings may cause a person to go undetected, resulting in serious injury.
After installation, the equipment manager must check according to the following terms, and
record the results.
4.1 Installation condition check
□ Controlled equipments can not hinder the implementation of security function, such as
blocking
the device to come into a halt.
□ BLPS can always detect the operators in the detecting area.
□ Calculate the safety distance accurately, the safety distance S=___mm.
□ Actual safety distance is larger or equal to the calculated values, the actual safety distance
___mm.
□ Do not use the BLPS in the flammable and explosive environments.
4.2 Wiring check before switching on power supply
□ Providing the BLPS with the specified power, if other equipment uses the same power, the
pow⁃er should meet the requirements and other equipments do not affect the working state of
BLPS.
□ The DC24V power should meet the requirements of the EMC directives, LVD directives
and the output requirements.
□ The power supply connecting should be correct, without reverse connecting.
□ The connecting of the cables of receiver and emitter should be correct, the signals lines
should be connected correctly.
□ There is no short circuit between sensor’s OSSD and DC24V.
□ All the signal lines are not connected to dangerous voltage.
□ The 0V and the shielded layer should be connected to the ground.
□ Use the cables provided by the company.
□ Connectors, wire terminals are connected firmly, without looseness.
□ Cables must mot be bent, cracked or damaged. The cables in the connector end should be
relaxed to avoid damaging connectors.
4.3 Operation check while the bender is stopped
□ When the test piece enters the detecting area and blocks the beam, BLPS should keep the
light-shaded state, when the test piece is removed, BLPS turns into light-passing state and
OSSD is on.
A. Place the test piece in the detecting area and block the L1, L2 and L3 beam respectively,
the indicator corresponding to L1, L2 and L3 in the receiver should be turned on.
