Instructions
WARNING:
HAZARDOUS VOLTAGE
CAN CAUSE ELECTRICAL SHOCK
AND BURNS.
DISCONNECT POWER BEFORE PROCEEDING
WITH ANY WORK ON THIS EQUIPMENT.
Operation permissible in switchgear cabinet with degree of protection
IP 54 only!
Applications
C575 is suitable for installation in controls for presses.
- Hydraulic presses DIN EN 693
- Eccentric and related presses EN 692
- Screw presses EN 692.
Functions and connections
The two-hand control unit C575 possesses two release circuits in the form of NO
circuits and two signal circuits in the form of NC circuits. Five LEDs indicate the
operating status and the functions.
The release circuits are closed by simultaneous operation (< 0.5 s) of the push-
buttons S1, S2. If one pushbutton is no longer pressed, the release circuits open.
They do not close again until both pushbuttons are no longer pressed and then
simultaneously pressed again.
1. Apply the operating voltage (UB) to the terminals A1 and A2. The operating
voltage must be de-energized with the operating energy of the press.
2. Close the feedback circuit:
Connect the bridge to Y11, Y12 or NC contacts of external contactors.
3. Connect the input circuit:
Connect pushbutton S1 to terminals Y21, Y22, Y23 and
pushbutton S2 to terminals Y31, Y32, Y33.

The unit cannot be started with the following faults:
- Short-circuit, e.g. between the pushbuttons
- Defective relay coils
- Conductor failure
- Welded contacts
The output relays do not pick up if
- the pushbuttons are not pressed simultaneously (< 0.5 s)
- only one pushbutton is pressed
- the feedback circuit Y11, Y12 is open.
