PowerLine User Guide
More Current = More Speed
This software selectable feature allows the use
of reverse acting single coil valves. When this
box is unchecked, the PowerLine will apply
less current to get higher system speed. This
feature is only available if Disable Coil B is
selected. The current, when the coil is "off",
will be the MAX current in reverse acting
mode.
Enable Active High -
(active when enable 'enable'
= true)
When this box is checked the PowerLine logic
is enabled when there is a high or > 5 VDC on
the enable input pin. When the check box is unchecked, the unit is enabled when there is a low or 0 volts on the
enable input pin. The unit is disabled when enable pin is not in the enabled state. This prevents driving the
outputs unless “More Current = More Speed” is unchecked. If unchecked, disabled causes max current. (Note:
The 'Enable Enable' check box must be checked for enable active to operate properly)
Enable the ‘Enable’ Input
When this box is checked the PowerLine will look at the ‘Enable In’ input to enable the controller. When this box
is unchecked, the PowerLine is always enabled.
Enable Direction
Use of the Direction input allows the user to use the full range ( resolution ) of the command input in each
direction when applicable.
This check box enables the (Direction) Coil B H In input to the controller. When selected, Coil B will be active
when the input is pulled high.
Ramp to 0 (zero) if Disabled
This check box determines the units behavior when the enable input is used and changes state. When this box
is checked, the ramp value and method in use with the selected algorithm is applied to turning off the output.
When this box is unchecked, the unit immediately turns off the output.
Anti-Stall - Current to 0 (Zero)
When the input RPM is less than the STOP RPM, the current will stay at MIN unless this box is checked, in
which case the current drops to zero from Imin without ramping. This option is only active in Anti-Stall mode.
Command Reverse Acting
This feature is available in “Anti Stall w Max Command” mode only. When checked, the Command Volts Min in
single coil operation demands 100 percent current and Command Volts Max demands 0 percent current.
Warning: It is dangerous to do this in dual coil operation, the Center Voltage will command 100 percent output.
