1 INTRODUCTION
1.1 Introduction
CiDRA Concrete’s SMARThatch System is the first and only device to
continuously measure and report the air content of fresh concrete in a truck
mixer drum while being transported from batch plant to job site.
This manual covers the basic installation, setup, operation and
maintenance of the SMARThatch System.
In all cases, local safety and operating practices take precedence over the
information contained within this document.
1.2 SMARThatch Mobile System, Hardware and Equipment
The SMARThatch System hardware consists of a drum-mounted sensor,
chassis-mounted receiver module, in-cab mounted display, cellular telematics
module, battery charger and associated cables/connectors.
The SMARThatch sensor is mounted to a hatch adapter panel that replaces
the existing drum access hatch as shown in Figure 1. Numerous hatch
adapter panels are available to fit a variety of different truck mixer drum styles.
The SMARThatch sensor is powered by a rechargeable lithium-ion battery
and communicates wirelessly to the SMARThatch receiver module which is
mounted on the back of the truck cab or to the truck frame as shown in Figure
2.
The SMARThatch in-cab display shows concrete air content (%), concrete
temperature (°F or °C), drum speed (rpm) and sensor battery charge level (%
remaining) as shown in Figure 3.
The SMARThatch telematics module uses cellular communication to
transmit measured data to a secure cloud server where it can be accessed
through web-based portal or through an API.
The SMARThatch battery charger is located inside the truck cab and is
powered by the truck 12 VDC power.
Note: The SMARThatch sensor housing is made of hardened material that is
well suited for the high abrasion environment inside a concrete mixer.
However, to prevent damage that would require sensor replacement, care
must be taken not to strike the face with a jackhammer, chisel, etc.

•For trouble-free, long-term performance, the SMARThatch System
requires regular inspection and cleaning of the hatch- mounted sensor.
When performing periodic inspections, take note of any damage to the
hatch, sensor, electronics enclosures, and associated interface cables. If
any damage is noted, take the appropriate corrective action depending
onthe situation – up to and including removal of the sensor from service
until repairs have been performed. Contact CiDRA Concrete Customer
Support (Section 1.4) for information regarding repairs and spare parts.
•The drum-mounted sensor with hatch adapter panel weighs
approximately 56 lbs (25 kg). Two-person lift is required. Use extreme
care and follow all procedures in this manual when installing and
removing the sensor from the mixing drum.

4 INSTALLATION
4.1 Installation Training
Satisfactory completion of an installation training program provided by CiDRA
Concrete is required prior to installing the SMARThatch system.
Following purchase of SMARThatch services, the installation training program
will generally work as follows:
•Customer designates installation personal and schedules initial
installation.
•CiDRA provides remote and/or on-site installation assistance and
training during the initial installation.
•The designated installation personal will receive a certificateof training
completion and approval for installation of follow-on SMARThatch Systems
Contact CiDRA Concrete Customer Support for more information (Section 1.4).
4.2 Preparation
In addition to the warnings and cautions in this section, refer also to the General
Safety Guidelines in Section 3.
4.2.1 Power Requirements
Ensure truck electrical power is turned off and truck battery disconnected prior to
working on the receiver, display and telematics.
DC input power requires the following:
Receiver Module:
9 to 16VDC, 1 Watt, (for Trucks with 12VDC Battery only)
In-Cab Display:
9 to 16VDC, 1 Watt
Telematics Module:
9 to 16VDC, 7 Watts
An overcurrent protection device (fuse) must be installed on the supply side of
the +12V ignition and +12V battery power inputs, with a fuse current rating of
10A to 20A.
Warning
12VDC Vehicle only

21798-01-EN Rev. 04 Page 14
4.2.2 System Operating Environment
* Sensor and Battery -4°F to +140°F (-20°C to +60°C)
Receiver Module -4°F to +140°F (-20°C to +60°C)
Display In-Cab -4°F to +140°F (-20°C to +60°C)
Battery Charging 32°F to +113°F (0°C to +45°C)
*Concrete temperature between 32°F to +122°F (0°C to +50°C)
Table 1 System Operating Temperatures
The SMARThatch sensor, receiver, and display are suitable for operation in
0 to 95% non-condensing humidity environments.
4.3 Sensor Installation
The following steps detail installation of the SMARThatch System.
4.3.1 Sensor Location and Orientation
The SMARThatch sensor is installed in place of the existing drum access hatch.
For accurate air and temperature readings it is important that the sensor is
installed in the proper orientation relative to the drum rotation direction. The
sensor assembly has an orientation label that points in the direction of rotation
when the drum is rotating in the charging direction (Figure 6).
Figure 6: Label Indicating Proper Sensor Orientation
4.3.2 Remove Existing Hatch or SMARThatch Sensor
Remove the existing mixer drum access hatch. Clean and inspect sealing
surface and nut plate per drum manufacturer’s recommended practices. It is
very important that the nut plate is in good condition and therefore should be
replaced if excessive wear or any defects are found, or if there is any concern
that its mechanical integrity is compromised.
If an SMARThatch sensor is already installed, use caution when removing, as
it is heavy (56 lbs / 25 kg) and can cause serious injury if mishandled or
dropped. Two (2) people are required for removal.
Loosen all retaining bolts and leave several in place while prying the hatch free.
Remove all bolts, except the bottom retaining bolt to help support the weight
before the hatch is lifted off the drum. See Figure 8 for example of retaining bolt.

21798-01-EN Rev. 04 Page 15
4.3.3 Install SMARThatch Sensor
Install gasket or sealing compound following drum manufacturer’s
recommendations.
The SMARThatch hatch adapter flange has slotted bolt holes on the top and
the bottom. At the nut location of the bottom slotted hole, partially install a
retaining bolt into the nut plate, engaging at least three threads and allowing at
least 3/8-inch (9.5 mm) gap between the bolt head and the outer drum surface
as shown in Figure 8.
With two (2) people, lift the SMARThatch sensor into position and in the correct
orientation. Slide the bottom slotted hole onto theinstalled bolt to help support
the weight of the sensor during installation as shown in Figure9.
Install the remaining retaining bolts and tighten following the drum
manufacturer’s recommended procedure.
Warning
WARNING: The SMARThatch Sensor is heavy (56 lbs / 25 kg) and
can cause serious injury if mishandled or dropped. Two (2) people
are required for installation and removal, see symbol below.

4.3.4 Battery Installation
Only batteries specified by CIDRA Concrete should be used in the
SMARThatch sensor, CiDRA P/N 21809-01, 7.2VDC, 98Wh.
To replace the SMARThatch sensor battery, remove battery cover by loosening
four (4) one-quarter turn screws (Figure 11), lift the battery cover off and remove
the battery from the sensor.
Check that the battery charge indicator located on end of the replacement
battery shows five bars indicating full charge (Figure 12). Line up the battery
terminals and insert the battery terminal side first making sure it is fully engaged
and secure. Replace battery cover and securely tighten four (4) one-quarter turn
screws.
The spare battery may be stored in the battery charger, so it is always
charged.

Figure 12: Battery Charge Indicator Showing Full Charge and Battery Terminals

21798-01-EN Rev. 04 Page 18
4.4 Receiver Module Installation
Determine a location for the receiver module where it can be mounted on a flat
surface that has a clear line-of-site to the SMARThatch sensor on the drum.
Avoid mounting where the wireless signal between the receiver module and the
sensor might be blocked by a metal obstruction, for example the water tank or
truck frame. Figure 13 shows an example mounting location.
The mounting location must also allow the 13 ft (4 m) receiver module cable to be
routed to the inside of the truck cab to the area where the telematics module will
be mounted.
Use self-tapping screws or equivalent to hold the receiver module securely
in place.
Figure 13: Receiver Module Mounted to Back of Truck Cab
