WARNING: This module is designed for connection to hazardous electric voltages. Ignoring
this warning can result in severe personal injury or mechanical damage. This product must
be reliably earthed and installed by qualied personnel in accordance with the prevailing local
electrical wiring regulations and safety standards.
The CD-20 controller mounts directly to the C-Series sample probe via the DC-2 coupling (Figure 2.1). The
DC-2 coupling should be hand-tightened to ensure that the internal retaining ring is not pushed out of its
groove. If the DC-2 coupling is over-tightened at the CD-20 hub, the motor shaft will not engage the DC-1
coupling on the probe.
Figure 2.1—DC-2 coupling
All eld connections are made to terminal block 1TB on the control card (Figure 2.2). Install wiring as
follows:
1. Connect power to 1TB-1 and 1TB-2.
2. Connect the ow pulse input contact to 1TB-5 and 1TB-6. If an open collector transistor driver is used,
connect the collector to 1TB-5 and connect the emitter to 1TB-6 (common).
