1. Introduction
The TIME/Versalift Digger Derrick Control System consists of a custom
Controller/Receiver (grey box), an optional T45 Radio Transmitter and/or an optional
T47 Cable Remote. An interface is also provided for an optional user-supplied
Emergency Override Panel. The main components of the Controller/Receiver are an
R1300+ (APCB-1225-10) circuit board, a PWM/V Converter Board, an S20 (APCB-
1458-xx) board, and a REX-900 radio receiver.

The Controller/Receiver’s software is custom-designed for the Digger Derrick
application. Various sensors mounted on the machine chassis send feedback information
to the Controller/Receiver. This feedback information together with the operator
commands determine the drive outputs to the Apitech™ electric-over-hydraulic valves.
A sophisticated computer program, permanently encoded into the firmware chips of the
Controller/Receiver, governs the mapping of inputs to outputs.

Features of the computer program include safety interlocks to prevent injury to
personnel as well as damage to the machine. The program incorporates a “restart” check
which ensures that functions do not actuate unexpectedly due to operator panel switches
being left “on” by accident.

All wiring to the Controller/Receiver is through waterproof circular M.S.
connectors on the outside of the fibreglass enclosure, to ensure that the NEMA 4X rating
of the enclosure is preserved. This manual describes considerations which should be
taken during installation and operation, and gives procedures for “tuning” the system to
match the exact characteristics of your hydraulic valves.
