9.5 Setup or Change on the Power Supply Board
NOTE: Remove the power supply board before you set up.
CAUTION: Do not forget to remove power to the instrument before you work.
9.5.1 A change in the Power to Pulse Generator
A change in the power to the pulse
generator is made by changing jumper
J1 positions (4-coupled) on the power
supply board between 13.5V and 24V.
NOTE: Do not fail to replace all four
sockets at the same time.
J1, J2, and J3 in Fig. 9.8
show an example of jumper
positions.
9.5.2 Configuring the Flow Signal Input Circuit for the Companion Pulse Generator
Referring to Table 9.2, set up the ow signal input
circuit for the companion pulse generator.
(See Fig. 9.8 for the location of jumpers J1, J2,
and J3.)
9.5.3 Input Frequency Division (hardware) Selection
Input frequency division (hardware) is
set up by selecting the position of
jumper J4 on the power supply board
for 1/1, 1/10, or 1/100.
Install the jumper socket into one of
positions 1/1, 1/10, or 1/100.
J4 in F ig. 9.9 sh o ws 1 / 1 (d e fau l t
setting).
