4.6 - Hardware Maintenance Instructions
Before sending the instrument back to factory check the following probable
causes of a malfunctioning Indicator.
Instrument with error indication on display
After turning the instrument on, it tests RAM and E2PROM integrity.
When at least one of these components presents some problem the display
shows the following error codes:
Err. 01 - RAM error
Err. 02 - E2PROM error
In case of RAM error, turn the instrument off and on to check if the error message
is displayed again. If the error remains, return the instrument to factory.
When there is E2PROM error, press the ENTER key and configure the instrument
again. Turn the instrument off and on to check if the error message is displayed again. If
the error remains, return the instrument to factory.
During configuration the display can show the Err.03 error message.
This error can happen when trying to assign a different configuration (analog
output or alarm) to an output already configured and enabled. In order to avoid this case,
do not forget to disable relays 1 and 2 before enabling analog outputs 1 and 2 and vice-
versa.
Note: When configuring a relay module as an analog output, the relay will be
activated and deactivated continuously.
Instrument with the display out
Check if power supply voltage is provided to terminals 23 and 24 of the Indicator.
Verify the integrity of fuse F1 of 2.0 A placed in the Power Supply Board as
shown in Figure 16. Due to its package it is necessary to check the fuse continuity in
order to detect if it is broken.
Instrument malfunction
Check if the Indicator is configured correctly by software and hardware (internal
jumpers).
Examine if the optional modules are connected in the right spots.
Check if the voltages on flat cable 1 as shown in Figure 23 are close to the values
in table 5 and if they reach the CPU Board.
