Press modules Type IH04
| Commissioning
Bosch Rexroth AG, Edition 08.2021, RE 63124-B
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 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 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 guarding of the overall machine/system are not active during
initial commissioning.
8.1 Bleeding the hydraulic system
▶ For bleeding the overall system, observe the operating instructions of the
machine and/or system into which the press module is installed.
▶ Switch the press module several times under 50% of the operating pressure
before placing it into full operation so that air which has remained in the
press module can exit.
Mechanical damage due to inadmissibly high acceleration of the hydraulic
fluid and the valve spools is thus avoided and the press module's life
cycle is increased.
