Speed Bias Offset
• Factory calibrated for 0 Vdc offset on ±3 Vdc range.
• All Woodward Speed controls operate with this bias output, so no calibration
should be required.
• Calibration may be required for other manufacturer’s speed controls.
Voltage Bias Offset
• Factory set for zero Volts DC.
• Configuration selectable ±1 Vdc, ±3 Vdc, ±9 Vdc range.
• Some regulators require a positive voltage bias offset because they cannot
receive a negative voltage bias command. Any bias offset calibrated into the
voltage bias will be displayed in the I/O status menu.
• The EGCP-2control will always reset to the voltage bias offset when off line.
