9.7
Faults concerning Supply voltage
No. Cause
Remedy
60
Operating voltage was below 20 VDC.
Check power supply.
62
Sensor voltage too low.
Check external power supply
(insufficient power ?).
Contact Roland Electronic Service Department.
9.8
Faults concerning PLC parallel inputs
No. Cause
Remedy
71
The parallel function is not possible, because the system
was configured for the “demo mode”.
Configure system parameter Measurement
operation to “external continuous measurement” or
“single measurement”.
72
The parallel function is not possible, because the system is
operated via the keyboard.
Finish the operation via keyboard and return the
system to neutral operation by pressing the menu
key.
73
The parallel function cannot be performed because a
fieldbus function is active, e.g. “teach-in” via the fieldbus
and “measurement start” via parallel inputs.
Wait for the completion of the fieldbus function or
finish it and repeat parallel function.
74
The parallel function is not possible, because a parameter
channel is open.
Close parameter channel.
9.9
Faults concerning Fieldbus interface
No. Cause
Remedy
80
The inserted fieldbus coupler is defective.
Recycle power, if the fault reappears then the
equipment has to be returned.
81
The commands come too fast via the parameter channel.
Always wait for the results of the parameter
channel transmission before transferring new data.
82
The fieldbus function is not possible to perform, because a
parallel PLC function is active , for instance,
“Measurement start” via the parallel PLC inputs and in
addition “Measurement start” via the fieldbus.
Avoid simultaneous operation.
83
The fieldbus function is not possible to perform, because
another field bus function is active at the same time, e.g.
“Measurement start” and “Program switching”.
Implement only one function.
84
The fieldbus function is not possible, because the
measuring mode is set to ”demo mode”.
Configure the parameter “measurement operation”
to “external continuous measurement” or “external
single measurement”.
85
The fieldbus function is not possible, because the menu
(keyboard operation) is operational.
Terminate the operation via the keyboard and
return the unit with the menu key to its basic mode.
86
The activated fieldbus function is not possible or disabled
in the system.
If the function is required, then it should be
selected under systems configuration.
87
The fieldbus function cannot be executed, because the
equipment detected double sheet (with configuration
”double sheet hold”).
Clear double sheet condition via fieldbus or via
keyboard.
88
The program number activated in the menu program
selection is > 255.
Select valid program number.
90
The selected sensor at the inputs sensor selection A and B
is not valid. Example: Sensor no. 4 is selected but only two
senors are configured.
Select the correct sensor.
91
The field bus function cannot be executed, because the
parameter channel is active.
Close Parameter channel.
