Section 4-2
Hard-wired Terminal Block
Be sure the wires connected to the hard-wired output terminals have a total
length of no more than 3 meters.
CONECT1/2: These signal lines are used to confirm that the NSH5 Cable is
connected to the Removable Box. Attaching the connector will
short the CONECT1 and CONECT2 pins. When using a PLC
I/O Unit, use these signal lines to confirm the connection.
ENB-CH1/2: These signal lines are used to confirm the key switch condition
when using the NSH5 in Teaching Mode. If the key switch is
turned ON, the internal relay is turned ON, which will short the
ENB-CH1 and ENB-CH2 pins. (The key ON/OFF position can
be checked using external contacts.) Use these signal lines
when using the enabling switch as described in
Appendix D
Recommended Enabling Circuits
.
24 VDC/0 VDC: Power to the NSH5 is supplied from the NSH5-AL001.
EMG1A1/EMG1A2
EMG2A1/EMG2A2
When the power is OFF, the internal relay (NC) is turned ON, placing the stop
switch line in loopback status.
When the power is ON, the internal relay (NC) is turned OFF, and the stop
switch line is connected to the NSH5.
Pin No.
