A circuit protection device located inter-
nally. Check main schematic for proper
size and type.
A single control used to set the threshold
sensitivity level above the ambient noise
pickup.
An internal 20 turn adjustment on the
PCA-II5 printed circuit card used to ad-
just the equivalent offset frequency of the
FTB500, 7 to 150 Hz.
An internal adjustment on the PCA-115
printed circuit card which is factory set to
turn off the offset frequency oscillator at
no flow.
A dual-in-line (DIP) switch located on a
PCA-112 board which is used to program
the module to accept an input frequency
range.
A multiple turn adjustment potentiometer
which is used to set the current/voltage
output signal with no flow to the desired
"zero" value (i.e., 4
