5.1 Before Powering On
WARNING: Follow Lockout/Tagout and other safety precautions when connecting or
disconnecting cabling, wiring, and equipment.
Each item below lists the manual Section(s) that will provide a reference for that specific item.
Also refer to Section 3.1 System Block Diagram and Section 4.5 Wiring Diagram.
WARNING: Damage may occur if the 24 VDC and 0 VDC Commons are improperly
connected.
1. Verify San Unit DIP switch settings (4.10)
P Verify that the SW1, SW2 and SW3 DIP switches visible on the side of each unit are set to
indicate the appropriate spindle number and options.
2. Confirm Interface (PLC) connection (4.7)
P Verify that the MNR Unit I/O interface wiring is connected to the corresponding PLC
terminals.
3. Check connections between the tool and the MNR Unit (3.2)
P Verify that the homerun cables connecting the tool and MNR Unit are secure. If the layout
contains moveable parts, 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 or other components in
the layout, then make appropriate adjustments.
WARNING: Do not make cable connections with the power on. Turn off all controller
power before attempting to connect or disconnect any motor cables or tool damage may
occur.
4. Check the input voltage (3.2, 4.6)
P Verify input power is properly connected (4.11.2).
P Ensure input power voltage to the MNR Unit is 24V DC.
P After turning on the power, verify the voltage again to ensure it has not dropped as a result
of loading.
NOTE: After an MNR unit is powered down, the power must not be applied again for at
least five (5) seconds. Repeated power up and power down may temporarily disable the
MNR unit. If an MNR unit does become disabled, keep the power off for five (5) minutes,
then power on again to reset the fault.
