Table 4.4 “Form for Recording Channel Voltage Measurements”. (Additional copies may
be made to use for spot readings or trial runs.) Check the diagram to see if the position is
now satisfactory. Once balance is apparently achieved, it is advisable to let the system
operate 24 hours to thermally stabilize the Measuring Head. Then make any necessary
adjustments and record the final position values on one of the book copies of table 4.3 or
4.4 and label accordingly. (This data will be valuable for future troubleshooting or
maintenance.)
When the desired final position of the Measuring Head has been obtained, return to
“Completing the Measuring Head Installation”, section 4.6, step b, to complete the System
installation.
4.11 REVERSING CABLE EXIT DIRECTION ON MEASURING HEAD
The cables are normally connected to the Measuring Head such that both cables point
upwards. This is to facilitate routing the cables through conduit. However, there are
instances when it is desirable to have the top cable on Measuring Head half “A” (cable A)
point downwards to allow for the installation of a shroud or weather protecting enclosure
directly above the Measuring Head. The following procedure is for changing the top cable
exit direction:
1. Disconnect ac power to the Metering Unit.
2. Disconnect the top cable from the Measuring Head.
3. Note the original position of the guide pins and guide sockets (located at the corners of
the connector). Remove the guide pins and sockets.
4. Gently pull out the connector pin housing being careful not pull excessively on the
delicate cable wires. Rotate the pin housing ½ a turn (180°) and reinsert into the
connector.
5. Reinstall the guide pins and sockets in a pattern directly opposite the original position
(i.e. replace the sockets with the pins and the pins with the sockets).
6. Reconnect the cables to the Measuring Head and reapply ac power to the Metering
Unit.
Warning:
With the system on a live bus, the ac power is off, and the cable disconnected from
the head, a shock hazard exists on the Measuring Head connector terminals.
