8. MAINTENANCE
The three-position device itself does not require any maintenance in addition to regular functional testing
and cleaning.
The emergency stop safety function must be checked monthly. All safety functions and mechanisms must
be tested regularly, at least once a year, to confirm that all the safety functions are working as they should.
Depending on the application, machine manufacturers may stipulate requirements for shorter maintenance
intervals. If this is the case, such requirements should be given priority. As a rule, it is recommended to
document all maintenance work.
To ensure that command buttons continue to function in the long term, it is advisable to regularly wash
them with a soft cloth and a standard (soap-based) multi-purpose cleaner.
The connection cable must be inspected regularly and replaced in case of damage. Make sure that the cable
is an original cable from ABB to ensure highest safety and reliability.
Caution
The degree of protection of the three-position device specified in the data sheet must be met during
cleaning.
The operating surfaces are made of soft, elastic and very thin material designed to be hard wearing. Using
abrasive cleaning agents or sharp-edged tools can weaken or penetrate the surface, which results in the
protection class being lost in a relatively short space of time. (Dirt and moisture may penetrate the housing)
The use of cleaning agents containing solvents should be avoided. This is not only to protect the surfaces,
but also to protect the health of employees.
Attention!
If the device is not working or is damaged, the device must immediately be put out of service. Please
contact your regular contact for maintenance work or your nearest ABB Jokab Safety customer service or
dealer. Do not attempt to repair the product yourself. Any attempt to interfere with the device will result in
a loss of warranty. A damaged product can affect the function and the safety and how it functions, which
may lead to serious injury.
