Chapter 5: Powering Up and Initial Checks
WARNING
DO NOT operate the press WITHOUT all safety guards and/or devices in place and
operational.
NEVER
enter the press ram area with power applied to the press unit.
Follow Lockout/Tagout and other safety precautions when performing maintenance or
connecting / disconnecting cabling, wiring, and equipment.
There is a possibility of receiving an electrical shock from this equipment, if used improperly.
5.1 Before Powering On
• Verify SAN Unit DIP switch settings (4.8)
Verify that the eight (8) DIP switches visible on the front of each unit are set to indicate the
appropriate press number and options.
• Check connection between tool and controller (3.4, 4.5, 4.6)
Verify that the homerun and extension cables (resolver/motor, load cell, brake and proximity
switches) connecting the tool to the SAN unit are secure. Ensure that each numbered set of
cables are connected to the identically numbered tool and SAN unit.
If the press application requires the press mounting fixture to move, visually inspect all
components to ensure that there is proper clearance and that cables have sufficient length. If
movement would create any excessive stress on a cable or create any potential for damage to
the system, then make appropriate adjustments.
WARNING: DO NOT make motor connections with the power on. Turn off all controller
power before attempting to connect or disconnect any motor cables or system damage
may occur.
• Check SAN Unit I/O cable wiring (4.7)
Connections with external control equipment are done between Main Unit I/O connectors and/or
SAN unit I/O connectors.
SAN Unit I/O connectors are still required when the system is configured with a Main Unit.
24VDC and limit signals for the press proximity switches are supplied through this
connector.
Verify that the I/O interface wiring is connected to the corresponding PLC terminals.
Remember, all inputs and outputs are wired active true low. All interface devices must
accommodate active true low connection for correct operation.
• Check the Input Voltages (2.1, 4.4)
Verify that the Input Power Connector(s) is properly wired and that the voltage to be applied is
within the specified range.
Verify that the 24VDC and 0VDC common wires are properly connected. Damage may occur if
wired improperly.
Be sure to check the previously mentioned items before turning the power on.
• Power Voltage Re-Checks
Re-check the input power voltage after turning the power on to make sure the voltage does not
drop due to loading.
Check again for loading when the Servo Press has started and the load is at its maximum level
for the press cycle (maximum power consumption time).
After powering the SAN unit down, the power must not be applied again for at least 5
seconds (1 minute recommended). Repeated power up and power down may
temporarily disable the SAN unit. If a SAN unit does become disabled, keep the power
off for at least five (5) minutes, then power on again to reset the fault.
