STARTING AND STOPPING

The DS9000 may be wired into the Start/Stop circuit of the motor controller or use the internal
DS9000 +5VDC supply. To start the DS9000, a DC voltage of between 5 and 25 volts DC must be
applied to terminals TB1-1 and TB1-2. Generally this can be obtained from the DC drive's Start/Stop
Logic Power Supply. For use with typical SECO drives, see Figures 2.2 to 2.8.
To start the DS9000 with the +5V DC supply available on TB1-10 of the DS9000, connect TB1-10 to
TB1-2, and TB1-12 to TB1-1. A dry contact can be placed in series with the connection between TB1-
10 to TB1-2 to allow Start/Stop control from a switch, relay, PLC or other type of interface contact
closure.
CAUTION
Do not connect the common connection on TB1-9 or TB1-12 to the common on TB3-2. If you
connect the start/stop of the DS9000 to the drive start/stop circuitry (as shown in Fig. 2.3 of the
Q7000), the drive reference common TB3-2 is connected to TB1-1. You can connect TB1-1 to either
the drive common or the DS9000 common but not both simultaneously without damage to the drive
and DS9000.
To start the DS9000 from the start/stop on the drive (such as the BRONCO II, SE2000, Q7000, etc.),
connect TB1-1 to the drive common (TB2-9 on the BRONCO II 160 series, TB2-11 on the SE2000, or
TB1-2 on the Q7000 series). Now that common is connected, connect TB1-2 to the drive terminal
point that is at a DC voltage level (i.e. –24V DC for the BRONCO II 160) when the drive has been
started. This would be TB2-3 on the Q7000 series. For these drives or others refer to the wiring
diagrams for the particular drive that you are using in their specific installation and service manual.
