the command analog input.

Analog Center Active (On/Off)

 When enabled, the  becomes the zero demand point.

 Coil A is driven from the center voltage to the max voltage and coil B is driven from the center voltage to the min

voltage

 This setting is used in Dual Coil Valve Control only. The is automatically turned

Coil Selection Active (On/Off)

 When the input is High, (+5V to Supply Volts) coil B is active and when Low (0V to 2.5V) coil A is active.

 This feature allows the full command resolution on coil A and B.

 As an example, it is used in the applications where a reciprocating action is triggered by a single high-low input.

Pot Center Error Detection at Initial Turn On

 When ON, the module verifies the analog input is in the center deadband range before enabling the output(s)

after the initial power up.

 Once the command is centered, the outputs will be enabled.

 This safety feature ensures that the system will NOT immediately go to the previous settings after cycling the

power.
