1.0 Introduction; 2.0 Wiring To Inputs & Outputs; 2.1 Inputs - CPI CMP 200 Series Service Manual

CPI Canada Inc.
3C.1.0 INTRODUCTION
This chapter describes the interfacing of the CMP 200® and CMP 200® DR X-ray generators to Bucky(s),
interlocks, room lights, a DR imaging system (if applicable), DAP, collimator lamp and tube stand locks, and
also describes the generator programming.
3C.2.0 WIRING TO INPUTS & OUTPUTS
THE INSTALLER MUST PROVIDE THE NECESSARY INTERFACING CABLES FOR WIRING TO
NOTE:
THE GENERATOR INPUTS AND OUTPUTS DESCRIBED IN THIS SECTION.
WARNING:
3C.2.1 Inputs
The Bucky inputs, interlock 1 and interlock 2 / tomo inputs, and room door interlock inputs are opto coupled.
This means that a relay contact, transistor, or other low-impedance switching device (≤ 100 Ω, 10 mA current
rating) must be connected across each of these inputs. Table 3C-1 defines the pin outs, polarity at the
terminals and the logic condition required for that input. If using a directional switching device, such as a
transistor, the polarity of the voltage seen by the switching device must be observed. This is shown in the table
below.
Refer also to figure 3C-1. This is a pictorial drawing of the J2, J4, and J11 inputs and outputs on the
H.V. auxiliary board.
Refer to 3C.2.4 for details on AEC connections.

NOTE:

LINE VOLTAGE IS PRESENT INSIDE THE GENERATOR AT ALL TIMES THAT THE MAIN
DISCONNECT IS SWITCHED ON. FOR SAFETY, THE MAIN DISCONNECT SHOULD BE
SWITCHED OFF AND LOCKED OUT WHILE CONNECTING ROOM EQUIPMENT.
DO NOT DEFEAT THE ROOM DOOR INTERLOCK, OR THE INTERLOCK 1 AND 2 INPUTS
UNLESS THE CORRESPONDING DEVICE IS NOT PRESENT. CONSULT THE
APPLICABLE REGULATIONS BEFORE DISABLING ANY EXPOSURE INTERLOCKS. DO
NOT VIOLATE ANY REGULATIONS FOR X-RAY SAFETY.
NEVER BYPASS THE X-RAY TUBE THERMAL SWITCH INTERLOCK.
OBSERVE IONIZING RADIATION PERSONAL PROTECTION AT ALL TIMES.
THE BUCKY 1 AND TOMO / BUCKY 2 OUTPUTS MAY BE INSTALLER-
PROGRAMMED. BUCKY 1 WILL NORMALLY BE PROGRAMMED TO
CORRESPOND TO THE TABLE BUCKY, AND BUCKY 2 WILL NORMALLY
BE PROGRAMMED FOR THE WALL BUCKY OR FOR TOMO.
