REMOTE DISPLAY - FRONT COVER SWITCH
The switch is installed on the front panel of the Remote Display. The heads of the two hex head screws have been
drilled through for the sealing wire. To prevent unauthorized switch activation after C&C parameters are entered
and the switch is set to setup mode, the switch’s cover is replaced and sealing wire is threaded through the switch
cover and the heads of the two hex head screws and secured with a W & M seal (see Figure 43).
Temperature Probe
The temperature probe used by the EMR
3
system for performing volume correction is connected to the two TP
positions of the terminal block located in the Display Head that is sealed by the mechanical method described
above. The temperature probe cable passes through the wall of the housing by way of one of two openings
provided. Strain relief for this cable is provided by a compression fitting called a cord grip. If the temperature probe
cable becomes disconnected, the system will display an error message and terminate the current delivery.
