4. MAINTENANCE
No routine servicing is required to ensure continuous operation, however should a system failure occur during operation,
then the most likely cause of malfunction is that of a requirement not being fully or correctly implemented. If a fault or warning
occurs, the cause should be determined in a logical and systematic manner and a guide is given below.
4.1. INITIAL CHECKS
1) Check that the power supply is of the correct type and value.
2) Check the fuse and that the power supply polarity is correct.
3) Ensure that all input and output connections to the plugs and sockets at the rear of the Model 2000
are satisfactory and the plugs are engaged firmly and in the correct sockets.
4) Ensure that all of the data entered via the keyboard or programmed via software is correct and that
all of the calibration data has been entered and is correct.
5) Switch off the power to the Model 2000 and check that all of the circuit boards are fully engaged in
their sockets and are positioned in the correct location.
6) Carry out a visual inspection of all wires and cables for obvious loose or broken connections.
7) Check that all external signal transmitters have the correct power supply voltages and that they are
operational.
