Between 0 - 3 links (inclusive) can be fitted to each board. This will give up to 8 Permutations of
configuration. Each configuration, varies the 'Output Signal' level of the transmitter board onto the Data
Bus, thereby giving it a unique signature, therefore we can have up to 8 transmitters with different output
signals on 1 Data Bus.
A second Data Bus must be used for machines that use more than 8 transmitters, e
.g . 5 section (4
telescoping section) boom machines. –

The CPU identifies each individual transmitter board from its unique signal off its corresponding Data
Bus. The CPU samples the Data from each transmitter in turn and if it fails to detect one or more it will
give a fault warning (audible), lock out the crane motions and display an Error code in the Status display
window (P 1).
Checking Data Transmitters
Any data transmitter failure is registered by the central unit as a 'Missing Transmitter
Identification
Signal' and displayed as a malfunction.
The CPU will react as follows:- Console 'Cut Ofr and Status display will show a code for most transmitter
failures it is prefixed with
'd='.
Note:- On a number of models a prefix of
'g='
will represent certain transmitters, i.e. machines with
4 telescoping sections. See Transmitter Identification Sheet.
See diagnosis sheets for the assistance in correcting malfunctions.
Transmitter Identification Sheet
A Transmitter Identification Sheet containing the various Models, Transmitter number, the motion they
monitor and the Error Code associated with it, is copied at the back of this publication.
Fault Diagnosis and Error Code Rectification
The following pages are to assist you in clearing Error Codes and carrying out general Fault Diagnosis on
the EKS 83. If these steps do not help you clear the problem and it becomes necessary to contact Grove
I
for assistance, a precise and detailed description of the malfunction will assist understand your problem
and could help you with future problems without having call for assistance. Such a description should
address the following points as a matter of course:
1. Exact malfunction description
2. Under what conditions does the malfunction occur
3. What is indicated on the five display windows :-
• Status Display (P 1) =
• Load(P2) =
• Load Cut-off (P3)
