SET● button, and switch with ▲button. "Anr"

Function Setting (continue)

7. Flow rate setting mode

Input set value. Input method depends on OUT1 output specification. It does not go into Flow rate setting mode when the integration pulse output is selected as OUT1.

Instantaneous switch output (oU1_0)

1. Press SET● button to input n_1(P_1) set value.

「n_1」and the set value appears in turn if previous OUT L/min

setting select reverse output mode. (「P_1」and the set value appears in turn when non-reverse output mode is selected)

2.Select set value by ▲button or ▼button. ▲button to increase the value, ▼button to reduce.

3. Press SET● button to input n_2(P_2) set value.

「n_2」and the set value appears in turn if previous OUT L/min

setting select reverse output mode. (「P_2」and the set value appears in turn when non-reverse output mode is selected)

4.Select the set value by ▲and ▼button as in 2. above.

5.Press SET● button to set the value.

6.＊n_1<n_2(P_1<P_2): Window comparator mode 「HIS」and hysteresis value appears in turn.

Press SET button after selecting hysteresis

●

with ▲ or ▼button. OUT L/min

▲button to increase the value, ▼button to reduce.

0 to 3% of rated flow value is adjustable as hysteresis value. If the difference between n_1(P_1) and n_2(P_2) is smaller than 6% of rated flow, max. set value of hysteresis is the half of the difference between n_1(P_1) and n_2(P_2).

＊n_1≧n_2(P_1≧P_2): hysteresis mode Hysteresis value is not set.

Integration switch output (oU1_1)

The value can be set up to 9999[m3 ×103 ], 999[m3 ], 999[		].
