Hardware Version 1.12 (2G/LTE-M)
for 12/24V

Hardware Overview

WINDCRANE is a remote monitoring wind measurement and reporting system. It consists of a web data/management portal and mobile app, and a logger/telemetry device housed in a compact weatherproof enclosure that contains sensor interface circuitry, processor and cellular communications module.
The device uses GSM/LTE-M cellular networks to communicate with the WINDCRANE web portal, where system setup and data analysis/download is handled (see separate documentation for the portal and app). The GSM/LTE-M antenna is built into the enclosure. There are internal slots for microSD card and SIM cards which are typically supplied pre-installed.
Standard screw clamp terminals are used for power and input signals. Two cable glands are provided for sensor and power cabling. One gland is fitted with a sealing plug in case only one gland is used.
1.1 Enclosure
The enclosure is a weatherproof box with latching hinged lid designed to meet IP67 rating. It is supplied fitted with 2 IP68 metal cable glands for power and sensor cables. If one gland is unused, it must be sealed using the supplied blanking plug.
The enclosure should only be opened in dry, clean conditions. It is generally only necessary to open the enclosure during installation to complete the wiring, or to change the SIM card or update firmware.
1.2 Power
WINDCRANE requires 12 or 24 VDC +/-25% from a regulated DC supply rated for at least 10 W, or from a 12 or 24 V battery system. The average consumption is very low, but during GSM/LTE transmit the consumption peaks can be higher. Also allow power for accessories and sensors (AUX+ output).
1.2.1 Permanent device installation
The unit is supplied with a cable terminated with a M12 connector for fast disconnection from the power  supply. If supplied cable is not used and the unit is permanently wired to the vehicle, a fuse rated at 500mAshould be used in series of the positive supply (for example Littelfuse 218.500MXP) . In addition to a protection fuse, means to be able to disconnect the power from the unit using a ‘all poles’ switch / circuit breaker or cable plug. Any device used as the disconnection device must be suitable rated for the voltage and power. A switch must be approved to IEC 60947-3; a circuit breaker must be approved to IEC 60947-2. Any external cables should have a temperature rating of +60°C The protection of the equipment may be impaired if the equipment is not used as specified.
1.3 Inputs
The WINDCRANE logger is typically used with a single wind speed sensor but provides inputs for up to 4 digital pulse signals and up to 6 analogue signals.
Inputs A1-A4 are pulse frequency counter inputs for anemometers.
Inputs B1-B2 are isolated pulse inputs for 12-24 V anemometer pulse signals, and internally drive the A1-A2 inputs respectively.
Input channels D1-D3 are sampled from on-board sensors. D1 provides barometric pressure, D2 provides internal temperature, and D3 provides internal relative humidity.
Input channel D4 is a resetting counter that is triggered by the A4 input. The count is reported, and the counter is reset at the end of each data interval.
Inputs D5-D10 are general-purpose analogue inputs and can be configured for 0-3.3V, 0-10V or 0-20mA (420mA) signals.
Input channel D11 samples the supply voltage at the PWR+ terminal.
1.4 Antenna
WINDCRANE has an internal multi-band GSM/LTE antenna built into the front/lid of the enclosure. This gives good performance for most areas with cellular network coverage.
Take care not to ob struc t the central part of the f ront o f the encl osure (un der the WI N DC RA NE l og o) wi th metallic objects and do not mount the WINDCRANE in a metal cabinet, otherwise the cellular signal may be affected.

1.5 Status Indicator LED
The WINDCRANE circuit board includes a green activity/status LED which indicates microSD card access, logging activity and communications status. This is only visible with the enclosure lid open. However, there is provision for adding an externally visible LED via PCB solder pads.

OK
Double short flash every 1 or 3 secs| Normal logging, transmit failed at last attempt
On solid for approx 10 secs during comms| Data transmit completed OK
Flashing for approx 10 secs during comms| Data transmit failed (possible network/SIM problem)
On solid for more than 10 secs| Data bulk upload in progress. Do not switch off.
On solid at power up| Firmware update in progress. Do not switch off.

1.6 Micro SIM Card
The microSIM card provides cellular network access, and slides into a socket next to the antenna connector.
The SIM orientation is printed onto the board next to the SIM socket. To insert a SIM, hold the SIM at the end opposite the cut off corner, with the gold-coloured contacts facing down, and gently slide the SIM into the socket and under the metal top until it stops.
If you use your own SIM, its APN parameters must be specified in the configuration file on the microSD card.
1.7 Micro SD Card
The microSD card is used for initial configuration, firmware updates, and data log files. The card socket is a push-to-eject type. To insert the card, simply slide it into the socket, with contacts facing down, until it latches into place. To remove the card, push it into to the socket slightly to unlatch it, then pull it all the way out. Be careful not to drop the card or get cards mixed up.
The microSD card holds backup log files and the SIM configuration file. See the reference section for SIM configuration details.
WINDCRANE is compatible with standard microSD cards up to 2GB capacity, formatted as FAT or FAT32. Do not use 4GB or larger SDHC cards.
1.8 Input Port Mode Jumpers
Input port jumpers are used to select the operating mode for each input by shorting together pairs of pins on the circuit board. There is a set of jumpers for each input, located near the respective input terminal. The jumpers are normally pre-set to the appropriate positions for the supplied or specified sensors.
Always power off the device before changing jumpers. Use fingers or needle nose pliers to lift off and reposition the plastic jumper caps.
Do not lose or discard any jumper caps. Unused jumpers can be “parked” by fitting them on to one pin only instead of bridging two pins.
Default jumper settings are shown in the table and photo below.

1.8.1 Input Mode Jumper Positions
The table below lists the input mode jumper positions for the supported signal types and ranges.

0 — 20 mA (or 4 — 20 mA)|

Installation

2.1 Mounting
For mobile or crawler cranes, WINDCRANE may be mounted at the jib end close to the sensor position, or elsewhere on the crane that allows cabling to the sensor and a power source.
Find a suitable mounting position that is protected against impacts and will not obstruct the operation of or access to other equipment. Orient the enclosure with glands vertically downwards if possible, and with enough space to open the enclosure lid for access to the wiring.
The WINDCRANE may be mounted to a structural member or plate using stainless steel or plastic straps through the loops/slots in the enclosure, or in a suitable cradle (not supplied). This prevents access into the enclosure, so complete any wiring first.
Take care to no t ob struc t the front of the enclosure under the WINDCRANE logo, as the antenna is located inside the lid. See Section 1.4 (page 4) for details.
Ensure the cable glands are tightened onto the cables after wiring. Check the lid sealing gasket is in place and not damaged, before closing the lid with the “claw” latch.
2.2 Power Wiring
For mobile or crawler cranes, the WINDCRANE should be powered from a 12-24 VDC auxiliary circuit that can provide power while the crane is operating or erected, or permanent power via a dedicated switch/breaker. The typical consumption is low enough that the WINDCRANE can be left running continuously while the crane is on site.
NOTE: The supply circuit must be fused for safety with a 500 mA T (time- delay / slow-blow) fuse.
Run a supply cable of at least 0.34 mm 2 (22 AWG) through the gland nearest the enclosure hinge and to the supply terminals and wire up as follows:

2.3 Sensor Wiring
Sensor wiring depends on the specific sensors being used. For a single anemometer with a volt-free contact type output (e.g. reed switch sensor), wire as follows:

For two sensors, connect the secondary sensor signal to A2 terminal. Connect the common/ground and cable shield to adjacent GND terminals.
For switch type sensors (reed switch or open collector NPN), the input mode jumpers must be set to the “Volt-Free Contact” position.
Some sensors have a low-voltage AC sine wave output. These are wired in the same way as above, but the corresponding input mode jumpers must be set to the “Low-voltage AC Sine Wave” mode.
Refer to Section 1.8.1 on page 6 for jumper positions.
