5. Check that the fault LED in the master console (See Dia. 7) is not on. If it
is, check to ensure that every console socket has a plug connected.
6. Rotate SW1 fully anti-clockwise and observing the loop output meter select
each clockwise position in turn, noting the loop output meter reading at
each position.
Note: If the loop output meter should read over 10 during this procedure
adjust LC1 to return the needle to 5. Please read the note and instructions
below before doing this.
7. Select the position of SW1 corresponding to the highest reading and note
that reading.
8. Using a screwdriver, rotate TC1 through 3600 and note the action of the
loop meter. If when rotating TC1 through one complete revolution, the loop
meter does not raise above the reading obtained at stage 6, rotate SW1
one position anti-clockwise and again continue from step 8.
9. When rotating TC1 through one complete revolution the loop meter should
show 2 positions when the meter is at its highest.
10. Rotate TC1 to obtain the highest reading on the loop meter.
11. To check if the loop is tuned correctly move TC1 a quarter of a turn in each
direction. The loop meter reading should fall in both cases. Re-adjust TC1
to give the highest reading.
The next operation is carried out to adjust the loop output meter to read 8.
This is to provide a datum reading for any future evaluation of transmitter
performance.
Note!
It should be understood that although the reading of the loop output meter is
being adjusted during this operation, the actual output of the transmitter and
the loop tuning is not being affected in any way. The only thing that is being
changed is the coupling of the output meter to the transmitter.
It is important that this is understood and that this operation is only carried out
during installation or replacement/re-siting of the loop. The core of LC1 is
made of carbon. It is very brittle so adjust it with care.
1. Locate LC1 (See Dia. 15).
2. Using a small screwdriver carefully rotate LC1 to adjust the loop meter to
give a reading of 8.
