6 Maintenance and service
 When designing this device, Hirschmann largely avoided using high-wear 
parts. The parts subject to wear and tear are dimensioned to last longer 
than the lifetime of the product when it is operated normally. Operate this 
device according to the specifications.
 Relays are subject to natural wear. This wear depends on the frequency 
of the switching operations. Check the resistance of the closed relay 
contacts and the switching function depending on the frequency of the 
switching operations.
 Hirschmann is continually working on improving and developing their 
software. Check regularly whether there is an updated version of the 
software that provides you with additional benefits. You find information 
and software downloads on the Hirschmann product pages on the 
Internet (http://www.hirschmann.com).
 Depending on the degree of pollution in the operating environment, check 
at regular intervals that the ventilation slots in the device are not 
obstructed.
 Internal fuses are triggered only in the case of a detected error in the 
device. In case of damage or malfunction of the device, turn off the supply 
voltage and return the device to the plant for inspection.
