Digital Inputs
The digital inputs allow control and registration of doors (open/close) or defrost or refrigeration (on/off) or any other
digital input information following the configuration of the recorder. By configuring the parameters the interpretation
of the corresponding status can be distinguished.
Power supply
The power supply can be connected directly to the vehicle or Carrier Unit battery. The included 3A (T) floating fuse
must be fitted in the +power line direct as close as possible to the power connection. The DataCOLD 500 T/R
recorders are suitable for a voltage between 10 - 36 Volt DC.
2.2 Mounting
The installation set of the DataCOLD 500 T/R recorder contains almost all components, required for a standard
installation with two temperature sensors. In addition to that some small materials like Silicon kit, PVC-conduit and
fixing materials for cable mounting are required.
- Preferably use, for both outside and inside walls the existing cable conduit. Alternatively use self adhesive cable
conduit. All drilled holes needs to be sealed with a suitable sealant.
- For future calibration requirements, it is advisable to allow enough spare cable to enable the sensor to be lowered
to the floor.
DataCOLD R-Version
The R-version is designed to be mounted within the cab of a vehicle in a DIN radio slot. The R-version is retained
in the mounting cage by spring locking plates fitted to each side. Fix the mounting cage by inserting it into the slot
and bending the fixing blades to secure it in the facia. Slide the recorder into the cage until it locks into position.
Once fitted into the cage, the removal procedure is to insert the keys provided into the keyways at each side of the
front face of the recorder to release the locks.
1. Select a suitable position for the DataCOLD, for example a free car radio slot in the dashboard or above the
driver. If there is no free slot we recommend to use the optional mounting kit. The mounting kit can be fitted as
shown below on top or underneath the dashboard.
2. Next, push the mounting frame into the slot and bend the metal flaps to secure its position.
3. Then install the sensors from the body to the driver’s cab. Please make sure to fit the cables along the chassis
with the harness so that they won’t be broken when tilting the cab.
4. Take the connector blocks off the back of the instrument and fix the cables and connect the power supply
directly to the battery according to the wiring diagram section.
5. Finally, before pushing the instrument into the slot, we recommend to test the function and to do a printout.
Optional junction box
When installing more than two sensors in case of a R-Version it is recommended to use a junction box making the
installation simpler. This way of installation is using one multi-core cable to connect the recorder with the junction
box. Inside the junction box the individual sensors and digital inputs are connected. Because pin 1, 3, 5 and 7 of
the sensor inputs are linked via ground, only one of these pins needs to be connected. For the digital inputs the
same is applicable for pin 2, 4, 6 and 8.
