VOBO TC COMPONENT OVERVIEW
Description of Components
Cover| The VoBo TC is rated IP66, NEMA 4X. These standards require that
the gasket be properly positioned, and the cover screws tightened to between
8.0 and 9.5 in-lbs. Do not over tighten the screws.
---|---
Entry Points| The VoBo TC has three (3) 7/8-inch diameter entry holes.
Three cord grips (cable glands) are provided. The cord grips accept 0.095-inch
to 0.290-inch diameter cable.
For cable that is of a larger diameter, alternate cable glands may be installed by the user, providing that they are rated watertight and to a -40o C to 80o C temperature range and are installed in accordance with the manufacturer’s specifications. Two (2) hole plugs are provided, to seal unused entry holes. This may be installed in place of the cable glands if fewer than three entry points are utilized.
**** The user may also remove the provided cord grip(s)and install ½ inch conduit fittings in accordance with the requirements of the National Electric Code (NFPA70) or the Canadian Electrical Code (CSA C22.1) and all local codes and regulations.
Battery & Battery Holder| A 13 Ahr Saft LSH20 D-size Underwriters Laboratories (UL) recognized lithium-thionyl chloride [Li-SOCl2] primary cell is provided. The following cells are certified for use with the VoBo TC.
Saft LSH20
Saft LS 33600
TadiranTL-2300
Tadiran TL-5930
The provided cell is user replaceable. Replacement cells MUST BE installed with the correct polarity. The polarity is marked adjacent to the battery holder. The Power Switch must first be switched to the “OFF” position while inserting or removing a battery. The battery should only be removed or replaced in an area which is known to be non-hazardous.
A Velcro tie down strip is provided to ensure the battery remains in place during transportation.
Power Switch| The switch activates/deactivates the power supply (the battery).
It should be in the “OFF” position when installing or removing the battery.
LED| The LED indicates successful completion of firmware initialization after power is turned
on and successful connection to the network has been made.
WUP Switch| Press this button briefly to interrupt the preprogrammed
sleep/wake cycle. This will immediately initiate the programmed reading of
connected Thermocouples and transmission of payload. This is useful for
checking readings while in the field or when calibrating sensors.
** The WUP switch will not function if the WUP terminal circuit is closed
MAGNETIC WUP| There is a magnetic switch directly underneath this label.
When the enclosure cover is on, a magnet can be used to activate this switch
and interrupt the preprogrammed sleep/wake cycle. This will immediately
initiate the programmed reading of connected
sensors and transmission of payload. A red dot has been affixed to the
exterior of enclosure marking the location of the magnet.
** The Magnetic WUP switch will not function if the WUP terminal circuit is
closed.
TC Terminal Blocks| Thermocouple terminal blocks. Generally, the red
wire of the Thermocouple is inserted into the negative terminal and the other
wire into the positive terminal. The terminal blocks accept 24-12 AWG stranded
or solid wires. Wire strip length should be 0.27 in (7 mm).
WUP Terminal| Can be used to connect an external dry contact switch.
When the switch position is changed (open/closed) the VoBo will wake up, run
through its program, read any connected thermocouples, and transmit the data.
The terminal blocks accept 24-12
AWG stranded or solid wires. Wire strip length should be 0.27 in (7 mm).
SERIAL| A RS232/UART terminal. Used for local configuration of the VoBo
TC, viewing the output locally, and recovering logged data.
** The area must be free of hazardous gases or materials prior to
connecting any device that is not certified for operation in the hazardous
area to the VoBo TC.
SERIAL Switch| The switch used to enable or disable communication
with the processor through the Serial terminal.
X5**| JTAG connection. Not for customer use.
**** The WUP button and Magnetic switch only function when the WUP I/O terminal is not in a closed position.
Field Installation
Set the Power Switch to “Off” when inserting or removing Thermocouple or
switches into the terminal blocks.
**The VoBo TC must be installed a minimum of 20 cm away from personnel.
**
Turn the POWER switch to the OFF position.
Remove any unnecessary cord grips. Install the provided hole plug into the unused hole by inserting the plug into the cord grip nut and tighten it to a torque of 40-45 in.lbs.
Ensure the thermocouple wires are stripped to 0.27 in (7 mm). Insert the sensor cable into the cord grip. The cord grips accept cable diameters of between 0.095 inch and 0.290 inch. Insert the thermocouple wires into the terminal block in accordance with the wiring diagram for that specific type of Thermocouple (see Thermocouple data sheet). Generally red goes to the negative position and the other color goes to the positive position. Tighten the terminal screw to 4.4 in.lb.
The VoBo TC cord grip sealing nut should be tightened to a torque of 50-55 in.lbs. If different cord grips or conduit fittings are desired, the installed cord grips may be replaced by the user with alternate fittings. The alternate fittings must be rated to provide a watertight seal around the cable and the enclosure opening.
To maintain the VoBo TC hazardous location certification and IP66 protection, the entry points to the device must be sealed so they are watertight.
The VoBo TC should be mounted on a secure, rigid surface capable of supporting the VoBo and sensor cables. If mounting on a wood surface, use 4 – #10 pan head wood screws. The minimum depth of penetration of the screw into wood is 1/2 inch. The minimum length of the screw is 1 ¼ inch. If mounting the VoBo TC on a metal surface, use 4 – M6 (1/4 inch) Socket Head Cap Screws and M6 Nuts with a locking washer. The enclosure requires 15 mm to clear the mounting hole. If mounting in a location that would subject the VoBo to corrosive elements, use stainless or galvanized fasteners.
Check LED for status. The LED will light green for 1 second following successful initialization of the VoBo. The LED will flash green twice for ¼ second each flash every time the VoBo attempts to join the network. The LED will light green for 1 second upon successfully joining the network. The LED will light red for 1 second if it fails to join the network after cycling through its configured FSB attempts and goes into its back off cycle. The LED will provide these indications only upon initialization of the VoBo (either through cycling power or resetting the microprocessor).
Press the WUP button to send another payload to confirm connectivity and transmission. Note the LED only functions upon powering up the VoBo. It will not light under normal operation.
The payload should be sent to your LoRaWAN network server where they can be viewed and confirmed that the VoBo TC is functioning properly.
Attach the VoBo cover with the provided screws. The screws should be tightened to 8 to 9.5 in-lbs.

Maintenance
User maintenance requirements of the VoBo TC is limited to replacing a depleted battery with a fresh battery. Please contact Volley Boast if any issues arise with respect to the performance of the VoBo TC.
