Modular Block System: Hydraulic Presses

6-145

- Bit 05:

Valve acknowledgement input parameter

S2 remains high

after the valve is switched on
Remedy: Check switch, cable, input card and all conditions
and then reset (input parameter

RSET)

- Bit 06:

Valve acknowledgement input parameter

S2 remains low after

the valve is switched off
Remedy: Check switch, cable, input card and all conditions
and then reset (input parameter

RSET)

INFORMATION
If no reaction time has been set for switching off the valve
(

TOff = 0), Bit 06 will remain set until the valve returns to its

start position. This is not a fault, but is important to bear in
mind.

- Bit 07:

Valve Y2 not in its start position (off) when switched on, i.e.
signal at input parameter

S2 • 1

Remedy: Check switch, cable, input card and all conditions
and then reset (input parameter

RSET)

- Bit 08:

Reset input constantly high, set too early, or

EIN = 1 or S1 = 0

or

S2 = 0

Remedy: Release reset button and press it again.
If this does not work, check switch, cable, input card and all
conditions and then reset (input parameter

RSET)

- Bit 09:

Valve acknowledgement input parameter

S2 goes to its start

position during operation (input parameter

S2 goes high while

output parameter

Y2 = 1)

Remedy: Check switch, cable, input card and all conditions
and then reset (input parameter

RSET)

- Bit 12:

No signal change detected from input parameter

S1. During

the working cycle of valve Y1 (valve switching on and off), the
valve has retained its start position (valve de-energised,
acknowledgement present).
Remedy: Check switch, cable, input card and all conditions
and then reset (input parameter

RSET)
