Wiring to Low Frequency Quadrature Register/Controller
1 . 10
C. EL0300 Scaler/Calibrator/Linearizer (SCL)
While the SCL can have multiple functions, in many
cases it is included strictly as a signal conditioner
(= ‘Jitter filter’). In those cases, only the calibrator
function is active.
 Pulser plug is removed. Pulser leads are connected
directly to TB2 on the SCL.
 Signal output cable is connected to TB1.
This diagram applies to the ELNC register, when the
flow meter/register are used
in non-hazardous zone .
It also applies to LectroCount™ and other lower fre-
quency registers with quadrature input.
D. EL0300 (SCL), EL2057 Energy Limited Power Supply (ELPS) & ELNC Register
When flow meter/ELNC register is
used in a hazardous zone, the
EL2057 (AC/DC power supply &
barrier, UL listed) must be used.
EL2057 is in a NEMA 7 enclosure
(Expl-Proof, but not water proof), so
it must be installed under roof or
inside a water proof cabinet.
 Pulser plug is removed. Pulser
leads are connected directly to
TB2 on the SCL.
 Signal output cable is connected
to TB1.
Note 1 : See CD1000 & CD1001 for installation of intrinsically safe apparatus.
Note 2 : Cable lengths are limited by entity parameters.
Note 3 : ELPS output option: Install U1, R3 & TB6.
E. EL0300 to non-Quadrature Register
Same as diagram D, but connect only signal channel A.
