Notes:

The specified values are only valid when using the system-related components specified in this data sheet. At pressures < 20 bar, higher tolerances have to be anticipated due to lower actuating forces.

Schematic diagram: Actuating system supplied internally

1)	When using the pressure transducer HM 20 cable version: Installation in P (pump) or MP1 (preload valve) in connection with electronic version "Actual pressure value input F". When using an external pressure transducer: Installation in the P1 line (preferably close to the actuator) and electrical connection via the central connector. When using a preload valve, the pressure transducer is to be connected to P1 or MP1.

Schematic diagram: Actuating system supplied externally

The representation shows an example with integrated electronics.

1)	The use of an anti-cavitation valve (check valve with 0.2 bar spring) is essential in order to prevent dry-running in the error case.

2)	Pressure transducer	Mounting options	Comment
	HM 20-2X/315-F-C13-0.5 (cable version)	P	Only in connection with actual pressure value input "F"
	HM 20-2X/...-.-K35 (connector version)	P1	Preferably close to the actuator

	3) Maximum pressure limitation must be provided by the customer!
	4) Observe upper limit for external pilot oil pressure! (see operating instructions), recommendation: 20 bar absolute.

Important notes on external supply:

In the case of an actuating system with external supply, the pump adjustment will - in case of voltage failure - not switch to zero stroke but to the negative stop (displacement of 100 % flow from the system to the tank). With an active fault message, it is imperative that the machine control reacts (e. g. switching off the drive motor of the pump, interrupting the external supply of the actuating system). The command values for pressure and flow must always be greater than zero (pcommand ≥ 3 bar, αcommand ≥ 5 %) as due to drift or tolerances, there is no exact "zero" pressure or "zero" swivel angle. Under unfavorable conditions, smaller command value presettings can lead to cavitation. The actual pressure value must not be less than 10 bar for more than 10 minutes (lubrication).
