Modular Block System: Hydraulic Presses

6-129

TOn:

Maximum permitted reaction time for switching on the valve
(in ms)
TOn = KF 001 ... KF 350 when VTyp = 0 (directional control

valve)

TOn = KF 000 ... KF 350 when VTyp = 1 (poppet valve)

Ensure you follow the guidelines given under “Safety
guidelines for input parameters

TOn and TOff ”

TOff:

Maximum permitted reaction time for switching off the valve
(in ms)
TOff = KF 001 ... KF 350 when VTyp = 0 (directional control

valve)

TOff = KF 000 ... KF 350 when VTyp = 1 (poppet valve)

Ensure you follow the guidelines given under “Safety
guidelines for input parameters

TOn and TOff ”

VTyp:

Type of valve to be monitored
VTyp = 0:

Monitoring a directional control valve

VTyp = 1:

Monitoring a poppet valve

(see also under “Function”).

RSET:

Error reset
RSET = 0/1 pulse edge: Reset fault

It will only be possible to reset an existing fault if
the valve is in its start (off) position (valve de-
energised and acknowledgement from valve is
present) and no start signal is present (

ON •1).

Output parameters

ENBL:

Enable flag bit
ENBL = 0: No enable issued

When the valve is switched off (input parameter
ON = 1/0 pulse edge), the enable is locked until
the valve returns to its start position (input
parameter

S = 1). This is not an error.

The block will cancel the enable immediately if it
detects a fault.

ENBL = 1: Enable

The block will set the enable if no fault has been
found and the valve is either in operation or is in
its start position.
