15.2.4 Replacing the External Temperature Sensor
Tools required: Torx key Tx10, pliers
Adjuvant: Loctite 274
External
Temperature Sensor
Open the housing as described and remove the protective cylinder.
Remove the protective plate from the main board by unscrewing the 4 Torx M3x6 screws with a Torx key size
Tx10. Disconnect the circuit board connector of the outside temperature sensor from the heating board. Using
the pliers, unscrew the defective external temperature sensor from the sensor foot. Wet the thread of the new
temperature sensor with some Loctite 274 and screw it in by hand. Reconnect the connection cable of the new
temperature sensor to the heating board. The plug snaps into place with a click sound. Screw the protective plate
back onto the columns of the main board. Perform a functional test, as described in the chapter “Functional Test”.
Be careful not to cant the protective cylinder with the cables between the load cell and the main board.
Close the housing as described. Alternatively, the outer temperature sensor can be exchanged for a version in a
stainless steel sleeve with a 0.5 m cable and a small protective shelter (Id-No. 32.15184.020100).
15.2.6 Replacing the M12 Connectors
Tools required: Socket size 17, crimping tool, Torx key Tx20, Torx key Tx10, slotted screwdriver, blade width 2 mm
All M12 connectors used are inserted from the front and have an M16 mounting thread. The mounting plugs
are delivered with straight cut-off wire and must be stripped to 10 mm before installation and fitted with wire end
ferrules. (We recommend wire end ferrules with plastic collars.)
The connectors can each be screwed with a size 17 socket wrench.
To change the connectors in the rain[e]H3 , the housing of the rain[e]H3 must be opened as described. Loosen
the corresponding wires from the terminals of the circuit boards and unscrew the old plug. After the new plug has
been screwed, the wires are re-installed according to the connection diagram. Then close the housing as described.
15.3 Functional Test
Plug the terminal block of the heating of the housing’s upper part onto the heating board. Connect the power supply
to the sensors and heating. Connect the rain[e]H3 to the PC via the USB service socket and start the rain[e]H3
Commander on the PC. Start the Diagnostic Tool (remote control with gear wheel).
Select the tab “Status” – To check the general operational readiness of the rain[e]H3 . Select the used COM serial
port and press the gear wheel button.
If the heating and sensor supply are connected, the connection between the main board and the heating board
has been carried out correctly and the housing heater has been plugged in, all status messages should be
acknowledged with OK. If the heating supply and/or the housing heater are not connected, the heating status
indicates an error. In this case, check all connections and repeat the status check.
