1
Switch Point

1000000000
- +
RELAY_LIMIT
1 – indicates current
value relative to full
scale
Button controls adjust relay switch point
in 10% increments.

1100000000
- +
RELAY_LIMIT
1 – indicates current
value relative to full
scale
When entering this function the ready-
to-capture LED pattern is presented
(0101010101). Pressing either button
precisely captures the current flow value
as the new relay switch point.

1110000000
- +
RELAY_POLAR
0000011111 = ON
above (default)
1111100000 = ON
below
Selects whether the relay is ON (ener-
gized) if the flow value is above the relay
switch point, or if the relay is ON (ener-
gized) when the flow value is below the
relay switch point. Pressing the buttons
toggles between the two options (default
= ON above switch point – typical for low
flow alarm).

Minimum
Flow Capture
1111110000
- +
CUST_FLOW_MIN
1 – indicates current
value relative to full
scale
When entering this function the ready-
to-capture LED pattern is presented
(0101010101). Pressing either button
captures the current flow value as the new
display
zero
point.
7
Maximum
Flow Capture
1111111000
- +
CUST_FLOW_MAX
1 – indicates current
value relative to full
scale
When entering this function the ready-
to-capture LED pattern is presented
(0101010101). Pressing either button
captures the current flow value as the
new display
maximum flow
point.
Note:
This mode is only valid if the DISPLAY_
RANGE_MODE (5) is “static.”

RELAY_HYSTERESIS_
EFFECT
0000011111 = apply
above
1111100000= apply
below
Selects whether the hysteresis is to be
applied above (default) or below the
relay switch point. Pressing the buttons
toggles between the two options.

Hysteresis
Value
1111111110
- +
RELAY_HYSTERESIS
1 – indicates current
value relative to
maximum 10%
hysteresis (MAX_
HYSTERESIS)
Buttons adjust the value of the dead
band effect. Increments in 1 percent of
switch point value. Default setting is
2% of span. Button range 0-10%. Wider
range available through RS232 interface.

Time Delay
to Activate
Relay or
Binary Pulse
1111111111
- +
RELAY_TURN_ON_DELAY
1 – indicates current
value relative to
maximum delay
(MAX_DELAY)
Time delay from when flow measurement
is greater/less than relay switch point, to
turn on relay. Increments and decrements
in 1 second steps [max. default setting 10
seconds when using buttons].*
