) The hydraulic power unit may be con-
nected to mains with a frequency of
60 Hz, but the resulting revolution rating of
approx. 3400 rpm is rather high. This can
not only lead to increased running noise,
but also to suction problems with small
piston diameters. Therefore it is recom-
mended that the viscosity of the pressure
fluid during operation shouldn‘t exceed 160
to 200 mm

6. Run-down
A certain pressure rise will occur due to pump motor run-down, if the pump is directly connected to a hydraulic cylinder via a pipe,
such as e.g. in the typical connection pattern for clamping equipment (connection block B...) and if the power unit is switched off
by a pressure switch as soon as a pre-selected pressure is achieved. The extend of this additional pressure rise depends on the
pre-selected pressure, the volume of the connected consumers and the pump delivery rate. If such pressure rises are undesired,
it will be necessary to reset the pressure limiting valve to match the shut-off point of the pressure switch. The result will be that all
excess delivery of the pump during run-down will be conducted to the tank via the pressure limiting valve.
Procedure for matching is as follows:
; Fully open the pressure limiting valve.
< Adjusting the pressure switch on highest value (turning the adjustment screw clockwise up to the stop).
= Start the pump (pressure gauge and all consumers connected) and turn up the pressure limiting valve until the pressure gauge
shows the desired final operation pressure.
> Turn back the pressure switch until the pump is switched off at the preset pressure (see =).
? Lock pressure switch and pressure limiting valve in position.
The effect of excessive run-down pressure may also be minimized by utilizing an accumulator or providing additional volume in
the consumer line. If the pump is running under full load, i.e. the preset pressure is close to the maximum permissible pressure as
listed in D 7900, then effectively no run-down will occur, as the pump will stop almost immediately after shut-off.
5. Motor protection against overheating
The load related current consumption differs in most operation conditions from the nom. current I
N
and is usually higher. Therefore
the set current I
set
should not be adjusted to I
N
, when utilizing an protective motor switch, but to I
M
which corresponds to the setting
of the pressure limiting valve (I
set
, 0.7 I
M
). This will cover situations where the motor is stalled as well as if there is no disabling signal
emitted at the end of an operation cycle (during S2 or S3-operation).
Attention: The protective motor switch doesn‘t offer any absolute protection against overheating, especially, if the immediate
ambient temperature is higher than approx. 40°C. Therefore the running and stand-still periods should be monitored
at least by an idiot light to make it recognizable for the operator. It is recommended to employ an electrical supervision
circuit, if a system is not permanently checked by an operator, which emits a signal and will automatically cut-off the
system either immediately or after an sufficient period in case of a malfunction (motor is energized even during an
intended stand-still period).
The guideline figures for the adjusted current I
set
do only apply if the winding is completely fluid immersed. This is the case only
if no more than 0.05 l (HC 1..), 0.25 l (HC 2..), 1 l (HC 3..), and 2 l (HC 4..) are removed from the pump. Otherwise, if more fluid is
removed per operation cycles, with the winding being no longer fluid immersed, the response time for the protective switch will be
too long due to a lack of fluid cooling. Therefore an supervision circuit (see above) is highly recommended if more fluid is removed.
4. Operation with 1-phase mains 230 V AC
The compact hydraulic power packs type HC for 3-phase mains
400/230V AC may be connected to 1-phase mains 230V AC when a
so-called „Steinmetz Circuitry“ is employed.
The performance will be approx. 30 ... 40% lower when compared
with type HCW and the operation capacitor must be bigger (e.g. HC 24
approx. 30 ... 40 µF, HC 34 approx. 60 ... 80 µF).
Pumps type HC equipped with this special, external circuitry are not
suited to replace type HCW, but may be employed if no 3-phase
mains is available and type HC must be connected to 1-phase mains
as an exception to the rule. This is only possible if the pump features a
/-circuitry for 230V, otherwise the !-circuitry for 400V must be
converted (see sect. 3.2).
Attention: The pump will not start against pressure! Therefore the
connected directional valves must provide a possibility to
start the pump against a depressurized system e.g. by
means of an idle circulation valve.

7.3 Initial operation and bleeding
The pump cylinders will be bled automatically if the pump runs or is switched on/off several times and the directional valves are
switched into idle circulation. Another way is to install a pipe fitting with a short piece of pipe and prolonged by a translucent tube.
The other end of the tube should be put into the filler neck, held firmly and sealed with a non-fluffing cloth. Now switch on the pump
and let it run until no more bubbles are visible.
Next after the pump cylinders are bled any air dragged into the system should be removed by opening the bleeder screws at
the consumers (if provided) until no more bubbles are detected or by operating all functions of the circuitry without load until all
cylinders, motors, etc. move steadily and without any hesitation.
7.4 Servicing
The hydraulic power packs type MP and directly mounted valves are almost maintenance free. Only the fluid level and the
insulation resistance of the motor winding should be checked regularly depending on operation conditions. The fluid should be
exchanged every year as a general rule, but more frequently if tests show aging or contamination.
7.5 Spare parts
Repairs (replacing service items) are possible by competent craftsmen. The motor can‘t be repaired or replaced by the customer.
Therefore if the motor is defect, the complete pump should be returned to our facilities for an overhaul. There are spare parts lists
available (E 7900..), pls. state your pump type acc. to the type plate.

Attention: The hydraulic power packs type HC are not suited for use with fire inhibiting fluids type HFA(B), HFC, HFD.. conforming
VDMA 24317 and biologically degradable pressure fluids based on polyglycole (HEPG).
Electrically hazardous: Any fluid types containing water must not be used (danger of short circuit).
Any fluids based on seed oil are not suited as the permanent contact with the hot motor winding (fluid immersed motor)
