EE244 Electrical Connections
Sensing probes
Depending on the type ordered, the EE244 can accommodate up to three sensing probes.
Plug the probes directly onto the M12 connector on the EE244 enclosure. Alternatively, install the
probes remotely by using 2 m (6 ft), 5 m (16 ft), and 10 m (33 ft) optional M12 cables, see accessories
in the EE240 data sheet.
Remotely installed probes shall point downwards.
Pluggable Antenna
Upon delivery the antenna ist mounted onto the EE244 enclosure. If needed, the antenna can be
unplugged and remotely installed with an optional 2 m (6 ft) antenna cable, see accessories in the
EE240 data sheet.
Power supply
• The EE244-A transmitter can be powered with 4 x 1.5 V, AA / LR6 alkaline batteries (not in the scope
of supply)
• The EE244-B transmitter can be powered either by 4 x 1.5 V, AA / LR6 alkaline batteries (not in the
scope of supply) or by external power unit. Select battery or external supply with the jumper J1, see
Fig.
8.
The external supply unit shall be connected to the EE244-B and EE244-R using a 4 pole M12 socket
(included in the scope of supply, accessory no. HA010707). Pin assignment of the female socket, see
Fig. 6.
• The EE244-R router requires external power supply, it cannot be battery powered. The J1 jumper
shall stay on the „EXT" position, see Fig. 8.
Important: Do not attempt to power the EE244-R router with batteries. This would disable all EE244-R
