Pilot Command “Non- Isotope”
Pilot command “No Isotope” is a magnetic control system designed to replace the conventional isotope control
system.
RX 120 V 22 Ah battery
This set consists of 10 Pb elements, delivering a total of 22 Ah at 120 V, a 16 A fuse, a 0 V – 120 V switch, a connector
for connection to the base of the crawler chassis.
RX 120 V battery charger
It consists of a box containing the 220V mains power cable, the charger/battery cable, a fuse protecting the primary
circuit, a switch with mains indicator and a needle ammeter.
Track expanders and centralizers
