Recorded
information
The leftmost red digit indicates the address of
the register and the three rightmost digits indi-
cate the "recorded value".
Register/ Recorded information
STEP
3 Operation counter. Shows the number of raise and lower operations.
Note! The control pulses given manually from the push-buttons are
not counted.
Registers 1 to 7 of the submenu are enabled when the communication
with SPA/LON gateway is established between voltage regulators.
These monitor registers show the transferred data essential for parallel
operation as described below.
(Note! These parameters have been incorporated since the program
version 118H)
1 Status information (SI) of all three regulators is available in the sub-
menu register 1, which enables simultaneous monitoring of all regula-
tors. The status information consists of:
- Right green digit (digit #1) shows always SI (1...5) from its own
regulator
- Middle green digit (digit #2) shows SI (0...5) from one of the other
two regulators
- Left green digit (digit #3) shows SI (0...5) from the other one of the
other two regulators
The meaning of the digit #1, #2, #3 depends on which regulator is
inspected. When using the factory settings of SPA-ZC 100s, the digit
numbers #1, #2, #3 are mapped according to the tables below:
Inspection of SI on SPCU 1D50 with address A10
(connected to SPA-ZC 100 xB):
Red digit
1
Inspection of SI on SPCU 1D50 with address A20
(connected to SPA-ZC 100 xC):
Red digit
1
Inspection of SI on SPCU 1D50 with address A30
(connected to SPA-ZC 100 xD):
Red digit
1
Status information:
0 = no communication with SPA/LON gateway
1 = the operation of the voltage regulator is blocked
2 = single operation
3 = waiting for establishment of the parallel operation
4 = parallel operation by using negative reactance principle (NRP)
5 = parallel operation by using minimizing circulating current (MCC)
