The regulator operates manually but operates incorrectly when

set on automatic

Manually run the regulator to the neutral position. Check for

voltage between the bottom of the

switch and

. This

is the sensing circuit supplying voltage from the output of

RCT1

on the rear panel. If this voltage is more than 10%

above or below the programmed voltage level setting of

the control, then the source is beyond the range of the

regulator. An absence of voltage would indicate a wiring

problem such as an open somewhere in the control power

supply. If these checks are correct, perform the following:
1. If the control will not operate automatically, verify that

the band edge indicators are functioning. (These are the

OUT-OF-BAND HIGH

and

OUT-OF-BAND LOW

LEDs

located on the front panel.) If they are not functioning,

check FC 56, Reverse Sensing Mode. Set it to

Locked

Forward

if it is not there already. Retry the automatic

mode of operation.

2. Verify that FC 69, Auto Blocking is set to

Normal

. Retry

the automatic mode of operation.

3. Measure the voltage from

TB3

(or on the

lower terminal board

TB2

if present).

A. A measurement of approximately the set voltage

value between

and

indicates that the

problem is in the control.

B. If there is no voltage present between

and

, the trouble is in the V1 disconnect or the ratio-

correcting transformer of the back-panel circuit.

Replace them.

4. Check the holding switch circuit.

A. Verify that the tap-changer will complete a tap

change by placing the

CONTROL FUNCTION

switch to

LOCAL Manual

and toggling the

Raise/

Lower

switch in the desired direction.

B. If the

Raise/Lower

switch must be held in the

Raise

Lower

position to complete a tap change,

the problem is in the holding switch circuit. If the

holding switch is not working, a Quik-Drive tap-

changer will do multiple taps until the tap change

time-out occurs.

C. Check for voltage between

TB3-HS

and

(

TB1-HS

TB2-HS

if they are present and

). When TB1

and TB2 are present, if voltage is present at

TB1-

and not on

TB2-HS

, the problem is in the back

panel wiring harness. Replace the orange

lead

from

TB1-HS

TB2-HS

. If no voltage is present

TB3-HS

(or

TB1-HS

when present), the problem

is in the control cable, junction box cover, or the

holding switch (located inside the regulator) itself.

Check cable continuity up to the junction box.

If it appears normal, the problem is the holding

switch. To replace the holding switch, see

documents

Maintenance Instructions

. If all appears to be in

order, the problem is most likely in the control, not

in the holding switch.

Check FC 56, reverse sensing mode

When there is no load current and the regulator will not

operate in automatic, check the

switch on the back panel.

If the

switch is closed and FC 56 is set for

Bi-directional

the regulator will not operate in automatic. The

switch

should be open for normal operation.

Check FC 69, auto operation blocking status

1. Check the

CONTROL FUNCTION

switch. The switch

should be on

AUTO/REMOTE

2. Verify that FC 69 is set to

Normal

. To check the FC 69

setting:

3. If not on

Testing with the voltage limiter ON and a limit value set

NOTICE

Equipment Damage . Be mindful of polarity when using

an external source . Polarity reversal will result in control

damage .

VR-T201 .0

When testing a regulator with external power, it is

recommended that FC 80, Voltage Limiter Mode be set to

Off

When testing in the auto mode with the voltage limiter on,

there may be problems getting the regulator to operate

in either raise or lower direction if the external voltage is

greater than the voltage limit settings.
