5 Troubleshooting/Frequently asked Questions
– Hydraulic and electrical power deviations of up to 5 percent from the data sheet are
possible due to the design.
– A leakage of up to 2 ml per hour is possible due to the design and no cause for concern.
– A sufficiently powerful power supply unit must be used for testing outside a vehicle.
Recommended output power: more than 3.000 watts.
– Sufficient cooling according to specification must be provided for testing outside a
vehicle.
– Permanent application of system pressure outside of normal use is not permitted.
– If a secondary casing pump overflows the ECP 160 pump at the test bench, this can lead
to starting difficulties for the ECP 160 pump.
– PWM signal: we recommend to use a push/pull power amplifier. With a low side switch
you could use the internal pullup.
– Cleaning:
– High pressure cleaning and compressed air are not permitted, do not use aggressive
cleaning agents (brake cleaner, etc ...).
– Cleaning with warm water, mild soap and brush is recommended. All entrances and
exits must be closed.
– Overtemperature behavior:
– The electronics automatically reduces the power when the permissible temperature
is exceeded until the permissible temperature/power ranges level off.
