Carrier DATACOLD 500 T/R - Manual (Page 5)

1.3 Printer
The thermal printer is installed in the right side of the recorder. Due to the so called “Plug and Play concept” the
printer can be retrofitted, at any time, without disconnecting the recorder from power. For retrofit, the existing
mechanism will be exchanged for a mechanism with printer. To remove the printer or the housing, press lightly the
release bar on the right hand side under the housing. The whole mechanism can be slid out carefully. Warning: In
the T-version the printer module must be disconnected via a cable connector. When inserting the printer module,
slide it in carefully until the lock catches.
Note: a print out must be torn downwards over the edge of the bottom plastic part. A colored line on the last few
feet (meter) of a roll indicates that the paper roll needs to be replaced. (Enclosure B )
2 Installation
In general DataCOLD 500 T/R Temperature recorders are supplied with all required components for a standard
installation. A standard installation includes the mounting of the unit itself and mounting and connecting two
Temperature sensors. Optionally 2 extra sensors and up to 4 digital (status) inputs can be connected. The main
steps of the installation are described in the following chronological order.
2.1 Positioning Connections
Temperature sensors
DataCOLD 500 T/R temperature recorders can only be used with temperature sensors supplied with the
DataCOLD 500 T/R package. Before the installation it is necessary to determine how many measurement points
are required to retrieve the desired information. Only by an optimal choice of the number and the position of the
sensors, can a sensible conclusion be drawn of the air temperature in an entire compartment.
The following items must be observed when planning:
- The Temperature sensor should not be mounted in a location without air circulation.
- The sensor position should be protected against bumping of load, doors, etc..
- The beam of light from the interior light must have a minimum distance of 18 inches (0,5m) to the sensors.
- At least one sensor per compartment and also one sensor in the air return is recommended. The best position of
a compartment sensor is in the middle under the ceiling at about 1/3 of the compartment length from the back.
- The compartment sensor should be mounted with the Carrier protection guard. This will allow sufficient air
circulation around the sensor.
