Description
● 90 mm, P-93 housing, DIN-Rail
mounting
● Positive-guided relay outputs:
– 3 safety contacts: 1 N/C for
“down stroke”, 1 N/O for “up
stroke” and 1 N/C for
“hydraulic pump on”
– 1 auxiliary contact (N/O) for
“overrun distance correct”
● Connection for
Test limit switch, top dead centre
switch and relay contact “down
stoke”.
Function Description
The PNKL provides automatic press
overrun monitoring on linear driven
hydraulic, pneumatic and fly wheel
presses. The overrun control is
carried out in conjunction with a test
limit switch automatically and
positively. This occurs every time the
control voltage is switched on.
