Pressure Setpoint has been reached. Activation and deactivation conditions based on the Pressure Feedback and the settings
of P4-36 to P4-40.
Direct-acting PID
The terminal activates when the feedback meets or exceeds the setpoint for the time set in P4-38.
The terminal deactivates based on the hysteresis level (P4-37), delay time (P4-39), and the pressure reached exit conditions
(P4-36).
When P4-36 = 0 (Hysteresis Above & Below), the terminal deactivates when the feedback falls below the setpoint – hysteresis
level or when it rises above the setpoint + hysteresis level for the time set in P4-39.
When P4-36 = 1 (Hysteresis 1-Way), the terminal only deactivates when the feedback falls below the setpoint – hysteresis
level for the time set in P4-39.
Inverse-acting PID
The terminal activates when he feedback meets or falls below the setpoint for the time set in P4-20.
The terminal deactivates based on the hysteresis level (P4-37), delay time (P4-39), and the pressure reached exit conditions
(P4-36).
When P4-36 = 0 (Hysteresis Above & Below), the terminal deactivates when the feedback falls below the setpoint – hysteresis
level or when it rises above the setpoint + hysteresis level for the time set in P4-39.
When P4-36 = 1 (Hysteresis 1-Way), the terminal only deactivates when the feedback rises above the setpoint + hysteresis
level for the time set in P4-39.

H3-01: Terminal A1 Signal Level Selection
Selects the input signal level for analog input A1.
No. Name Setting Range Default
H3-01 Terminal A1 Signal Level Selection 0 to 3 0
Setting 0: 0 to 10 Vdc
The input level is 0 to 10 Vdc. The minimum input level is limited to 0%, so that a negative input signal due to gain and bias
settings will be read as 0%.
Setting 1: 0 to 10 Vdc Bipolar
The input level is -10 to 10 Vdc. If the resulting voltage is negative after being adjusted by gain and bias settings, then the
motor will rotate in reverse.
Setting 2: 4 to 20 mA
Setting 3: 0 to 20 mA
n
H3-02: Terminal A1 Function Selection
Selects the input signal level for analog input A1.
No. Name Setting Range Default
H3-02 Terminal A1 Function Selection 0 to 26 0
n
H3-03, H3-04: Terminal A1 Gain and Bias Settings
Parameter H3-03 sets the level of the selected input value that is equal to 10 Vdc input at terminal A1 (gain).
Parameter H3-04 sets the level of the selected input value that is equal to 0 V input at terminal A1 (bias).
Use both parameters to adjust the characteristics of the analog input signal to terminal A1.
No. Name Setting Range Default
H3-03 Terminal A1 Gain Setting -999.9 to 999.9% 100.0%
H3-04 Terminal A1 Bias Setting -999.9 to 999.9% 0.0%
