Figure 6-6. Interposing Relay Diagram (Optional ESTOP Wiring Method)
The relay is the type that when the coil is NOT energized, the contacts are
open. When the coil is energized, the relay contacts are closed. The ESTOP
button is normally closed (i.e. closed when it is NOT pushed). The relay coil is
always energized when the ESTOP switch is closed (NOT pushed), so relay
contacts are closed in normal operation. When the ESTOP button is pushed,
the ESTOP switch opens, so relay contacts open, shutting down the unit.
Magnetic Pickup Input
The magnetic pickup input accepts a speed signal over the range of 3 to 35 volts peak and 32 to 10,000
hertz. Magnetic pickup input terminals are listed in Table 6-7.
Table 6-7. Magnetic Pickup Input Terminals
Terminal Description
31 (MPU+) Magnetic pickup positive input
32 (MPU–) Magnetic pickup return input
Contact Sensing Inputs
Contact sensing inputs consist of 1 emergency stop input and 16 programmable inputs.
The programmable inputs accept normally open, dry contacts. Terminal 2 (BATT–) serves as the common
return line for the programmable inputs. Information about configuring the programmable inputs is
provided in Section 4, BESTCOMSPlus
® Software.
Contact sensing input terminals are listed in Table 6-8.
