Checking the operation of MAINFUF and PILOTFUF
1. Simulate normal operation conditions with three-phase voltage on the main fuse group
and the pilot fuse group. Ensure the values are equal to their rated values.
2. Decrease one of the three-phase voltages on main fuse group or pilot fuse group. The
voltage change must be greater than the set value for
MAINFUF or PILOTFUF signals are activated without any time delay.
3. Set normal conditions as mentioned in step 1. MAINFUF or PILOTFUF signals should reset.
4. Set
5. Apply three-phase voltages with the value slightly below
6. Decrease one of the three-phase voltages on main fuse group. The voltage change must
be greater than the set value for
7. After more than 5 seconds increase the measured voltage back to the value slightly below
USealIn level. MAINFUF signal should not reset.
8. Slowly increase measured voltage to the value slightly above
resets.
9. Record the measured voltage and compare with the set value

11.8.4.1

Verifying the signals and settings

Make sure that the function is connected to SMAI function with U3P signal.
Delta supervision function has 6 different modes of operation. Proceed as follows to test the
function in a particular mode.
1. Set the following parameters:
•
•
•
•
•
•
•
2. Set the constant voltage input of UL1 = 63.5V at 0° and UL2 = 63.5V at 120° and UL3 at
63.5 -120° secondary at rated frequency.
3. Based on the mode of operation, carry out the following changes on input condition of
Step
Each mode is given for increase and decrease operation. (3-a and 3-b)
