• The control with communications options allows the user to completely control the regulator through the SCADA system.
The SCADA system may place the regulator in a blocked state, thus inhibiting any further tap-changer operation initiated by
the control. Options include:
• Normal • Blocked
• Normal refers to normal automatic operation. Blocked refers to a state when automatic operation is inhibited.
• Example: This function can be used to perform a desired amount of voltage reduction and then disabling of the tap-changer
(inhibit additional operations) for an indefinite time period.
• The operator may change the state of this code by entering the level 2 security at the control and pressing the Edit/Reset
key. If SCADA has the control blocked, the operator may override the SCADA system by changing FC 69 from blocked to
normal, or, if the operator chooses to block automatic operation, FC 69 can be changed from normal to blocked.
• Refer to the Control Features: SCADA section of this manual for additional information concerning the SCADA interaction
with the control.

• Three levels of remotely activated latching voltage reduction are available.
• The percentage of voltage reduction to be performed is programmed at FC 72. Remote activation is then accomplished
through SCADA communications.

0 2 NA 0.0 0.0 10.0
• Three levels of remotely activated latching voltage reduction are available.
• The percentage of voltage reduction to be performed at Remote Level #1 is programmed at FC 73. Remote activation is then
accomplished by applying a signal to the appropriate input terminal when FC 70 is set to remote latch.
• See the Control Features: Analog SCADA section of this manual.
