For example, in a bi-directional system, to span the 0 to 2.5k Hz
output from –100 GPM to +100 GPM, with 1.25k Hz being 0 GPM,
set the FL 100H and FL 10KH inputs as follows:
FL 0H = –100.0
FL 25KH = 100.0
For example, to span the 0 to 2.5k Hz output from 0 GPM to +100
GPM, with 1.25k Hz being 50 GPM, set the FL 0H and FL 25KH
inputs as follows:
FL 0H = 0.0
FL 25KH = 100.0

ERRORS
Two independent SPDT (single-pole, double-throw, Form C) relays
are contained in this module. The relay operations are user
configured via software to act in either a flow rate alarm, signal
strength alarm, error alarm or totalizer/batching mode. The relays
are rated for 200 VAC max. and a have current rating of 0.5A
resistive load (175 VDC @ 0.25A resistive). It is highly
recommended that a slave relay be utilized whenever the Control
Relay ISO-MOD is used to control inductive loads such as solenoids
and motors.
TOTALIZE mode configures the relay to output a 50 mSec pulse
(contact changeover) each time the display totalizer increments
—
divided by the TOT MULT. The TOT MULT value must be a whole,
positive, numerical value.
