8. Arm the injector. When the Mechanical Stop is in position, mea-
sure the wiper voltage on the white/yellow wire of the mechanical
stop pot. The voltage must be 0.860 VDC +/-0.020 VDC. If voltage
is within specification, skip to step 14.
9. Disconnect one of the mechanical stop motor leads. Manually
move the Mechanical Stop plate forward approximately 1/8 inch
(3.2 mm).
10. Advance the plunger until the plunger position pot wiper voltage
(terminal 2) is 1.010 VDC.
11. Manually reverse the Mechanical Stop plate into the plunger plate
until the mechanical stop microswitch opens (noted by an audible
click). The DVM can be used on the microswitch to detect when
the microswitch opens.
12. Disengage the Mechanical Stop pot and adjust for 0.860 VDC.
13. Reengage the pot gear, and tighten the pot bracket screws.
Reverse plunger to the rear limit. Disconnect DVM from head,
then reconnect the Mechanical Stop motor lead.
14. Remove injector power. Ensure that all pot screws are secure,
then install the cable bracket on the rear casting.
15. If required, attach the metal clamp and head cable on the cable
bracket.
16. Secure the wires and head cable with cable ties.
17. Reassemble the injector head.
18. Ensure that the proper syringe size is selected (look at the indica-
tors on the injector head). If the incorrect syringe size is selected,
press RECALL, 50, RECALL, then select the proper syringe size.
