Prosafe Electronic Time Delay Unit
Examples
For a 2 minute delay, start the short range configuration and set the
range to 7 for a 300 second maximum and the time to 4 for 40% of the
maximum.
For a 30 minute delay, start in the long range configuration and set the
range to 6 for a 3000 second maximum and the time to 6 for 60% of the
maximum.
Upon Installation
Lubricate code barrel assembly with light oil or spray, for example,
WD-40® or alternative product suitable for application. Check for
correct operation.
Maintenance
Every Week
Check the correct operation of the switching circuit. Also check for
signs of abuse or tampering. Inspect the unit for damage. Replace the
unit if damage is apparent.
At Least Every Six Months
Isolate all power. Check for any sign of wear or damage, for example,
cam assembly wear or contact oxidization and replace if apparent. Clean
out any accumulation of fine dirt, and so on. Lubricate code barrel
assembly with light oil or spray, for example WD-40 or alternative
product suitable for application.
Assessment of the operating environment can require the unit to be
lubricated more frequently. Reinstate the power and check for correct
operation.
Repair
If there is any malfunction or damage, do not attempt to repair it.
Replace the unit before machine operation is allowed.
