Testing And Maintenance - IDEC SE1L Manual

Safety Precautions Safety Precautions
Installation
x Install the SE1L on a stable surface or structure to
prevent displacement of the sensor.
x Install the SE1L securely so that screws do not loosen
due to shock or vibration. (Recommended tightening
torque 3N m). Displacement may degrade protection
performance.
x Determine the safety distance before installing the SE1L.
After installing the SE1L, use a test piece for all protection
zones to check the sensing functions. (Calculating safety
distance : see page 13)
x After installing the SE1L, to prevent entry into the
protective zone, use protective materials such as safety
guards and light curtains.
x The reset switch to reset the interlock function should be
installed far from the protection zone.
x If several SE1Ls are installed on the same sensing plane,
mutual interference may occur. For countermeasures on
mutual interference, see page 16.
x Provide enough space for installation and maintenance of
the SE1L.
x Do not cover the front of the optical window with glass or
transparent cover, otherwise detection characteristics of
the SE1L may be impaired.
x SE1L will not operate without initial configuration.
x Minimum sensing width differs according to the distance.
For details on performance specifications see page 6.
x The stability of the SE1L increases by delaying the
response time of the OSSD signal but the sensing
performance decreases for moving objects. Before using
this function, be sure to carry out risk assessment.
Wiring
x Be sure to turn off all the power before wiring.
x When using converter power, make sure to use power
that satisfy the following requirements.
1) The rated output voltage is within 24V DC±10% (SELV
circuit, overvoltage category II)
2) The circuit between primary circuit and secondary
circuit is reinforced insulation or double insulation.
3) The output holding time is 20 ms.
4) The power supply must comply with electrical safety
and electromagnetic compatibility (EMC) regulations
requirements of each country, state, and district.

SE1L
Safety Laser Scanner
x All input/output cables must be located away from power
cables and high voltage cables.
x To control safety-related machine or system, use OSSD
output. Because warning zone output (warning signal) is a
non-safety signal, do not use for safety purposes.
x Only use cables made for the SE1L. (For details see page
17.)
x Use an exclusive cable for connecting OSSD output wire
cable and safety-related machine or system.
Installation
x A password is used for configuring the safety function.
Only an administrator or operator should be able to use
the password.
x Perform test operation and check the configuration
before using the SE1L.
x The operator must record the changes made in the
configuration. SLS Configurator report function is
available. For details, see the user's manual.

Testing and Maintenance

x The operator should perform the following tests or
maintenance based on the checklist.
1) Pre-operation inspection
2) Operation inspection
3) Daily inspection
4) Periodic inspection
This checklist is a basic guideline for performing
tests and maintenance. The operator should perform
additional tests and maintenance if necessary.
x Stop the machine if failure occurs during tests.
x Clean the optical window if any dirt is found, ask for
repair if damaged.
x Do not drop the SE1L. Otherwise damage or
failure may occur and performance cannot be
guaranteed. Also, injury may occur.
x SE1L cannot be sold, imported, or used in the Federal
Republic of Germany until December 2013.
