Protection class according to DIN EN 60529	Version “K4”, “K72L”, “K73L”		IP65 (with mating connector mounted and locked)
	Version "C4"		IP66 with mating connector mounted and locked
Maximum coil temperature ³⁾		°C	120

¹⁾	Special voltages available upon request
²⁾	The switching times are measured according to ISO 6403 with HLP46, ϑ_oil = 40 °C ±5 °C and refer to 5% pressure change. With different oil temperatures, variations are possible!
³⁾	Due to the surface temperatures of the solenoid coils, the standards ISO 13732-1 and EN 982 need to be adhered to!

Actuation of the manual override is only possible up to a tank pressure of approx. 50 bar. Avoid damage to the bore of the manual override! (Special tool for the operation, separate order, material no. R900024943). The simultaneous actuation of both solenoids at a duty cycle of 100 % is impossible. When operating both solenoids, a maximum duty cycle of 10 % is admissible.

The shut-off of the solenoids creates voltage peaks, which can be reduced by the use of suitable diodes.

In the set-up mode, a H position can be achieved by controlling both coils (only with the 4/3 directional seat valve with the spool symbol “E”). In order to avoid an overheating of the coils, (according to VDE 0580) in the intermittent operation S3, a duty cycle of 10 % may not be exceeded with a play time of 5 minutes or 50 % at 70 seconds!

Operation with reduced power:
after the switching and achievement of the switching position (approx. 200 ms), the electric power can be reduced to 8 W (e.g. by means of PWM technology).

In the electrical connection, the protective earthing conductor (PE, grounded) is to be connected in accordance with the stipulations.
