4.1 General instructions
4.1.1 Before commissioning
·
Switch off the power supply before connecting or discon
necting plugs (otherwise this could lead to functional
damage).
·
Commission only a valve terminal which has been fitted
and wired completely.
·
Make sure that there is a sufficient supply of fresh air
(cooling) for the following operating conditions:
when the maximum number of valves are fitted
when the maximum operating voltage is applied
when the solenoid coil is constantly under stress.
·
Please observe the following instructions for building up
pressure in the complete supply.
4.1.2 Pressure increase in the complete supply
Warning
If the build−up in pressure of the auxiliary pilot air is too
slow or delayed, this may cause the actuators to perform
sudden unexpected movements under the following condi
tions:
if the compressed air is switched on with a safety
start−up valve (slow build up of pressure) and
when there are electric signals (e.g. after EMERGENCY
STOP).
This can cause damage to the machine or system and even
injury to human beings.
·
Supply the auxiliary pilot air externally via the pilot
control connection 12/14 (3...7 bar).
