Relay (CONTACT) Output
Totalized pulse signals and warnings can be output using the relay.
Signals can be allotted independently to each of the 4 contacts (relay channels, 1 to 4).
The output logic of relay channels 1 to 4 can also be independently inverted.
[Operation]
Desired operational output for each relay channel can selected from the list below.
BREAK : Relay always open.
MAKE : Relay always closed.
FW INTG
(+ totalized pulse output) : Relay closes once for each rise in the totalized count on
the forward flow side.
Relay operation time can be changed by setting the width
of the totalized pulse.
BW INTG
(- totalized pulse output) : Relay closes once for each rise in the totalized count on
the reverse flow side.
Relay operation time can be changed by setting the width
of the totalized pulse.
ROFF (no received signal) : Relay closed during warning for no received signal.
B.D. (break down) : Relay closed during break down failure warning.
B.D. or ROFF : Relay closed when warning is generated for either no
received signal or failure.
HI-LMT (upper limit warning) : Relay closed when upper limit value is exceeded.
For reverse flow determination is based on absolute
value.
LO-LMT (lower limit warning) : Relay closed when lower limit value is exceeded.
For reverse flow determination is based on absolute
value.
FW-DRCT (forward flow) : Relay closed when there is flow in forward direction.
BW-DRCT (backward flow) : Relay closed when there is flow in backward direction.
HI-RNG (high range) : Relay closed when range status is high.
LO-RNG (low range) : Relay closed when range status is low.
