3 Safety advice
Depending on the technical circumstances and the time under and at which the solenoid valve
is mounted, adjusted and commissioned, in each case you have to take into account particular
safety aspects
If, for example, the valve works in an operational chemical plant, the potential hazards of commis-
sioning have another dimension in case this is carried out for test purposes on a „dry“ part of the
plant in the assembly room.
Since we do not know the circumstances at the time of mounting / adjusting / commissioning you
may find advice on hazards in the following description which are not relevant to you.
Please observe (only) the advice which applies to your situation!
3.1. Personal protection
3.1.1. Safety advice for mounting
We wish to point out expressly that the mounting, the electrical installation and the adjustment of
the solenoid valves and the accesories must be carried out only by trained specialised personnel
having mechanical and electrical knowledge.
Don`t move off the coil from the tube by switched on power supply.
At first switch off all the devices / machines / plant affected by mounting or repair.
If appropriate, isolate the devices / machines / plant from the main.
Check (for example in chemical plants) whether the switching off of the devices / machines /
plant will causes potential danger.
If appropriate, in case of a fault in the solenoid valve (in a system which is in operation) inform
the shift foreman / safety engineer or the works manager without delay about the fault, in order,
for example, to avoid an outflow / overflow of chemicals or the discharge of gases in good time
by means of suitable measures!
Before mounting or repair, remove the pressure from pneumatic / hydraulic devices / machines
/ plant!
Drain the conduit from medium.
If necessary, set up warning signs in order to prevent the inadvertent starting up of the device /
machine / plant.
Observe the respective relevant professional safety and accident prevention regulations when
carrying out the mounting / repair.
Check the correct functioning of the safety equipment ( for example the emergency push off
buttons / safety vales, etc).
