SOLUZIONE SOLARE LM3485 Litemeter 420 TC Pro Device

GENERAL DESCRIPTION

The LITEMETER 420 TC PRO (LM1-420 TC PRO) is a calibrated cell temperature compensated with strictly selected electronic components to ensure maximum precision.
Its monocrystalline silicon cell is laminated with small micro prismatic glass for photovoltaic modules and E.V.A., this improves its durability and stability of measurements over time.
His output signal is 4-20 mA to ensure reliability and a continuous signal that testifies a correct working. To know more about signal line reliability, refer to paragraph 4 of our document downloadable at this link:
https://soluzionesolare.com/products/analog-solar-radiation-sensor-litemeter- current-pro/

PIECE’S LIST

LM1-420 PRO
M8 3 pin male connector (specify when ordering)
Aluminium fastening clamp
Mounting screws for the fastening clamp
Fixing screw for fastening clamp on profile/modules

CONNECTIONS

The connector is a female 3 pin M8 standard. The male connector is not included, but it can be found in commerce: anyhow, if you desire it you can order it to us.
The IP67 3-pin circular female connector carries all the signals from the LM1-420 TC PRO as in Tab. 1 and Fig. 1, that shows a fron t view of the female connector wired to the sensor (or a back side view of the male connector):

#	Name	Description	Cable colors
1	–	–	–
2	–	–	–
3	SUPPLY +Vin	Power supply input, + 9…30Vdc – See tab. 2	Blue
4	I out (-)	Current Output ( – )	Black

The compliance voltage depends by the burden resistor (datalogger input impedance) with the relation: voltage = 8 + impedance*0.02
The voltage supply has to be equal or greater than the compliance voltage.
Verify the input impedance of your DataLogger. Here below a table given to see DataLogger compatibility:

Input burden [Ohm]	Min. supply voltage [V cc]
20	8
100	10
150	11
250	13
500	18
1000	28

Tab. 2

MEASUREMENT

The signal can be read with an amperemeter placed in series to the output pole of the instrument, or with a datalogger with a 4-20 mA input.

CALIBRATION

It is recommended to calibrate this instrument after the first year of use and successively, every three years. Some “inclusions” may be present and clearly visible in the protective encapsulation resin. This is due to the resin coating process and do not affect overall performance and/or accuracy.
Important: for monitoring bifacial PV modules, please specify when ordering, a sealed cover will be provided. For bifacial application, the case presents a hole with a diameter of a few mm, this hole is terminated by a transpiring membrane whose purpose is the barometric compensation to avoid condensation.
DON’T PERFORATE. WARRANTY VOID IF REMOVED OR PERFORATED.
