MAX PRESSURE IN ML/SEC IS 6895
A pressure limit above 6895 kPa (kilopascals) was entered while
using the ml/sec Flow scale. This message appears when using 200
ml syringes and the kPa Pressure scale. Press RESET, then enter a
value no greater than 6895 kPa.
MAX PRESSURE IN ML/SEC IS 8274
A pressure limit above 8274 kPa (kilopascals) was entered while
using the ml/sec Flow scale. This message appears when using 150
ml syringes and the kPa Pressure scale. Press RESET, then enter a
value no greater than 8274 kPa.
MECHANICAL STOP FAILURE
The Mechanical Stop has not positioned itself correctly, or, has taken
too long to move into position. Remove and reapply power, then
attempt to operate the unit again.
Service Procedure:
1. Remove power from the injector, then remove the injector
head covers. Manually move the Mechanical Stop drive
belt to ensure freedom of movement; then look for
mechanical interference, broken connections, or other
damage to the Mechanical Stop motor, drive system, and
potentiometers.
2. If the condition persists, replace the Mechanical Stop Drive
Card.
3. If the condition persists, replace the Servo Control Card.
4. If the condition persists, replace the injector head.
MIN PRESSURE SELECTABLE IS XXXX
A pressure limit of less than the minimum selectable for a given pres-
sure scale has been entered. Enter a pressure limit value no less than
the minimum allowable. (See matrix of acceptable pressure limit value
ranges).
MIN VOL ALLOWED FOR 60 ML IS .5
A Volume of less than .5 ml was selected while in the 60 ml syringe
system. Enter a Volume value of no less than .5 ml.
MIN VOL ALLOWED IS 1 ML
A Volume of less than 1 ml was selected while in the 150 ml syringe
system. Enter a Volume value of no less than 1 ml.
MINIMUM DURATION ENTRY XXX.X SEC
Injection Duration must be at least the value shown in order to deliver
the selected Volume at the selected Flow Rate. Set the Injection Dura-
tion at any value greater than or equal to that shown, and less than
650.
