Original Automatice voltage regulator AVR R726 for leroy somer alternator
The additionnal Module R 726 enables to operate the following automatic voltage regulators
the 1ST FUNCTION being VOLTAGE REGULATION) into a so said "4 FUNCTIONS" regulation system :
the 2nd FUNCTION being the POWER FACTOR("COS ϕ ") REGULATION, using an additionnal C.T., when the alternator is paralleling with the mains.,
the 3rd FUNCTION being the BALANCE (EQUALIZATION)
OF VOLTAGES before paralleling (U = U) which is
generally realised by a synchronizer controlling the remote
voltage trimmer of the automatic voltage regulator,
the 4th FUNCTION (working with the 3rd) is parallel operation with other(s) alternator(s) equpped with the same
module R726 during voltage equalization before paralleling with the mains.
The module must be installed close to the voltage regulator (inside or outside of the machine).
It is connected to the voltage regulator in lieu of the remote voltage potentiometer of the AVR.
This remote voltage trimmer may be then connected if necessary to the Module R 726.
DESCRIPTION
The Module R 726 has 2 terminal strips of 10 terminals
consisting in FASTON LUGS (1/4") and mumbered 1 to 10
from left to right when facing the terminal strip.
TERMINAL STRIP J1 :
. term. 1-2 : OUTPUT FOR VOLTAGE REGULATOR MONITORING . connected in lieu of remote voltage trimmer
of voltage regulator.
. term. 3-4 : connection of remote voltage trimmer (see 3.1 for values). Short these terminals if no pot. is used (jumperST1).
. term 5-6 : INPUT OF COMMAND: "U=U" OPERATION when synchronising . external contact C1 . total impedance
of circuit loop to be ≤ 5 ohms , 50 Hz or 60 Hz.
. term. 7-8 : INPUT OF COMMAND "COS ϕ REGULATION"when paralleling with the mains.External contact C2 ; total impedance of circuit loop to be ≤ 5 ohms, 50 Hz or 60 Hz,
. term 9-10 : remote pot. to adjust power factor , short these
terminals of external pot. is not used (jumper ST2).
