INTRODUCTION

HD2013.3 is a precipitation detector based on the capacitive principle. The capacity value of the sensitive element changes according to the surface dampened by raindrops.
An integrated heater keeps the detector dry, evaporates water, and prevents false signals caused by fog or dew. The heater also activates at low temperatures, melting the snow and allowing detection of snow precipitations by using an ambient temperature sensor.
The instrument’s external circular dome acts as a windshield for the sensor, preventing false indications.
An auto-calibration algorithm compensates for variations in the response due to the dirt that can accumulate on the sensitive surface.
The instrument has a digital RS485 output with MODBUS-RTU or proprietary protocol, a 0/4…20 mA (0…10 V on request when ordering) analog output and a voltage-free contact output. The contact output is activated when the sensor detects precipitation in progress.
The detector has an IP68 protection degree.
Supplied with fixing bracket for ∅ 30…50 mm mast.
Optional bird spikes (to be requested when ordering the detector) can be mounted.

INSTALLATION

Use the supplied accessories to mount the instrument. The bracket can be fixed to a ∅ 30…50 mm mast, both vertical and horizontal, thanks to the double drilling on the bracket. Place the detector far from buildings, trees, etc…, taking care that the space above is free from any object that could obstruct the detection of the precipitation. Keep the sensor clean.
3.1 ELECTRICAL CONNECTIONS

The instrument has an 8-pole circular connector and uses the CP2013.2… optional cables, with the 8-pole connector on one side and open wires on the other side.

Connector| Function| Wire color
CP2013.2… cable
---|---|---
1| Voltage-free contact| Green
2| Power supply positive (+Vdc)| Red
3| RS485 B/+| White
4| Voltage-free contact| Blue
5| RS485 A/-| Brown
6| Analog output positive| Yellow
7| Power supply negative (GND)| Grey
8| Serial ground| Black

To ensure good noise immunity, it is recommended to connect the cable shield to the ground (GND).

RS485 connection:
By default, the instrument has MODBUS address 1 and communication parameters 19200, 8E1. Different parameters can be set using the proprietary protocol or the MODBUS-RTU protocol. Current analog output: By default, the current analog output is 4…20 mA, with
4 mA = sensor-sensitive surface completely wet
20 mA = sensor-sensitive surface completely dry
With the commands of the proprietary protocol, it is possible to set the range 0…20 mA for the output and reverse the direction of the output, so that when the sensor-sensitive surface is completely wet the output is 20 mA. In case of measurement error, the output goes to 22 mA. Voltage analog output (optional):
By default, the voltage analog output is 0…10 V, with
0 V = sensor-sensitive surface completely wet and
10 V = sensor-sensitive surface completely dry
With the commands of the proprietary protocol, it is possible to set the range 2…10 V for the output and reverse the direction of the output so that when the sensor-sensitive surface is completely wet the output is 10 V.
In case of measurement error, the output goes to 11 V. Contact output:
There is a normally open voltage-free contact between pins 1 and 4 of the connector (green and blue wires of the optional CP2013.2… cable). The contact closes when the sensor detects precipitation in progress.

CONFIGURATION AND MEASUREMENT

The configuration of the instrument and the reading of the measurements can be done via the RS485 serial output, both with the proprietary protocol and with the MODBUS RTU protocol. In the first 10 seconds after the instrument power on, it is always active the proprietary protocol.
After 10 seconds from power on, the operating protocol is activated, which by default is the MODBUS-RTU protocol.
It is possible to keep the proprietary protocol active even after 10 seconds from power on by sending before the 10 seconds expire, the command @ of the proprietary protocol. The proprietary protocol can be set as operating protocol by means of the CP0 command.
The commands of the proprietary protocol and the registers of the MODBUS-RTU protocol are described in detail in the following chapters.
Precipitation measurement: To determine if precipitation is in progress, the instrument detects the percentage of dry sensitive surface of the sensor:
100% = sensitive surface of the sensor completely dry
0% = sensitive surface of the sensor completely wet
When the percentage of dry sensitive surface of the sensor falls below a configurable threshold value (default 95%), the instrument indicates that precipitation is in progress. The threshold value can be modified with the command CRTnn of the proprietary protocol or by using the MODBUS holding register with address 5.
The indication of precipitation in progress ceases when the percentage of dry sensitive surface of the sensor rises above the threshold plus a configurable hysteresis value (default 2%) and after a configurable delay time (default 2 minutes).
The resolution with which the percentage of dry sensitive surface of the sensor is detected is 1% by default. The resolution can be set to 0.1% with the command CRLRn of the proprietary protocol or by using the MODBUS holding register with address 16.
The instrument discriminates between rainfall and snowfall based on the measured ambient temperature. If the ambient temperature is lower than a configurable reference temperature (default 2 °C), the precipitation is considered snowy.
The detection sensitivity can be adjusted with the command DRSn of the proprietary protocol or by using the MODBUS holding register with address 20.
Automatic calibration of the precipitation sensor:
The instrument can be set so that the precipitation sensor calibration is automatically performed at regular intervals; this allows compensating for any drift of the sensor due to temperature changes, aging, and dirt deposited on the sensitive surface.
The correction applied by each automatic calibration is limited to a maximum value (configurable), so as to avoid erroneous calibrations when the detected value differs too much from the estimated value.
By default, the automatic calibration is enabled, with 30 minutes intervals and 0.1% maximum correction. In order to change the automatic calibration settings, see the chapters on the proprietary protocol and MODBUS-RTU protocol.

PROPRIETARY PROTOCOL

To use the proprietary protocol, it is necessary to connect the instrument to the PC via an RS485/USB (e.g. RS51K) or RS485/RS232 converter and use a standard serial
communication program. In the serial communication program, set the COM port number to which the instrument is connected and the communication parameters as follows:

• If the MODBUS-RTU protocol is set as the operating protocol in the instrument (default), set the Baud Rate 57600 and the parameters 8N2 in the serial communication
  program, then power cycle the instrument and send the command @ within 10 seconds from the instrument power on.

• If the proprietary protocol is already set as the operating protocol in the instrument, it is possible to operate with Baud Rate 57600 and parameters 8N2 by sending the command @ within 10 seconds from the instrument power on, or you can let the 10 seconds pass without sending the command @ and operate with the communication parameters set in the instrument (default 19200, 8E1).

To change the instrument configuration, the serial command CAL USER ON must be sent first (the instrument replies with USER CAL MODE ON). The command CAL USER ON is automatically disabled after a few minutes of inactivity. If the settings should be only read, the command CAL USER ON is not required.
Below is the list of the serial commands.

MODBUS-RTU PROTOCOL

By default, the instrument has MODBUS address 1 and communication parameters 19200, 8E1. The address and the communication parameters can be changed by using the appropriate serial commands of the proprietary protocol or, alternatively, directly with MODBUS commands by changing the value of the Holding Registers described later.
The MODBUS-RTU protocol, if set as the operating protocol (default), is active after 10 seconds from the instrument power on.
In order to change the instrument configuration using the MODBUS-RTU protocol, the value 1 must be written first in the Coil number with address 1.

MAINTENANCE

In principle, the precipitation detector is maintenance-free thanks to an adaptive self-correction algorithm. However, it is advisable to carry out a periodical (at least every two years) visual inspection to check for any soiling of the sensitive surface. If necessary, clean the sensor surface with a moistened soft cloth. For more resistant dirt, a non-aggressive detergent or ethyl alcohol can be used.
