5.1.2 Mains power supply
WARNING: Disconnect mains power supply before beginning these
procedures.
Both power supply units (please see section 8.1 for a detailed description) are
equipped with fuses and voltage selection blocks;
check all fuses and voltage
selection blocks to ensure their are properly rated for the power mains and
change them as required to match mains voltage
.
All mains power supply protection fuses are conveniently located on the rear panel
and are easily accessed (see figure 6.2): to check or replace a fuse, disconnect
equipment from power mains
, unscrew fuse cover and pull fuse out of socket.
The following fuses are used:
TEX500-LCD
@ 230 Vac/115 Vac
TEX1000LIGHT
@ 230 Vac/115 Vac
Main power supply
(fig. 6.2 – items [20] and [35])
(2x) 16A type 10x38
(2x) 25A type 10x38
Service power supply
( fig. 6.2 – item [32])
(1x) 1A type 5x20
(1x) 2A type 5x20
Table 5.1:
Fuses
Ensure that the equipment is appropriately set for available mains voltage (supply
voltage rating is reported in the Final Test Table) as follows:
disconnect equipment
from mains
and ensure that the voltage selection block of the power supply located
on the rear panel (see fig. 6.2 - item [30]) is set to the appropriate voltage; change
setting as required.
The main power supply unit is the full-range type and requires no voltage setup.
When supply voltage is other than 230 Vac and might cause erratic operation (say,
less than 200 Vac), it may help to move jumper JP3 on the PFC controller board
from position 2-3 to 1-2 (see PFCPSL1000 diagram, item [6] in figures 9.1 and 9.3
and detail in figure 5.1 below).
