7�1 First commissioning
For commissioning, proceed as follows:
▶ Make sure that all hydraulic connections are closed and all electrical
connections are connected.
▶ Immediately depressurize the machine/system if hydraulic fluid still leaks
despite proper assembly.
▶ Commission hydraulic components only if they are fully installed.
▶ Allow the press module type IH04E with integrated electronics to acclimatize
for some time prior to commissioning as the electronics might be damaged
by the generation of condensed water.
▶ Electrical connections must be checked for proper condition by or under the
guidance and supervision of a specialized electrician before the initial or any
re-commissioning.
▶ Before switch on, check whether the protective grounding conductor of all
electric devices is firmly connected according to the connection diagram.
When commissioning the press module type IH04E on a machine/system,
first of all commission the electronics that might exist and then the hydraulics.
When commissioning the electronics, the hydraulics (power unit, valve etc.)
must be switched off in order to prevent damage of the hydraulic components
caused by incorrect wiring and malfunctions of the electronics.
Ensure a mechanical restraint function between the tools (EN ISO 16092,
par. 5.3) or move the cylinder piston to a fall-proof parking position if the
safety equipment of the overall machine/system is not active during initial
commissioning.
▶ Ensure that all pressure valves except the pressure relief valves .150/.151
are set during commissioning, as these are set to minimum in the condition
as supplied.
Pressure relief valves .150/151 are pre-set in the condition as supplied to
350 bar and secured against unauthorized adjustment, see Table 7.
▶ To limit damage in the event of a malfunction, start the first movement
attempts with the lowest possible pressure.
7�2 Bleeding the hydraulic system
▶ For bleeding the overall system, observe the operating instructions of the
machine and/or system into which the press module type IH04E is installed.
▶ Switch the press module type IH04E several times under 50% of the operating
pressure before placing it into full operation so that air which has remained in
the press module type IH04E can exit.
Mechanical damage due to inadmissibly high acceleration of the hydraulic fluid
and the valve spools is thus avoided and the life cycle of the press module
type IH04E is increased.
