ProStar325 Service Manual
Publication date 8 May 2003

It is important for operator safety and proper
operation of the ProStar 325 UV/Vis Detector that
you use the power cord supplied, together with a
properly grounded 3-wire power strip.
3.16 Fuses
The ProStar325 contains two fuses which are located at the back
of the instrument. To replace a fuse, disconnect the detector from
the power supply, and replace the blown fuse with one of the type
and rating as indicated in the Specifications section of this
manual or on the silk screening adjacent to the fuse holder.
The fuses have a code marked on the cap (e.g. T3.15AH250V).
This refers to the fuse characteristic (‘T’ - time lag, ‘F’ - fast
acting), the current rating (‘x’ amperes), the breaking capacity
(‘H’ - heavy, ‘L’ - low) and the voltage rating (‘y’ volts). This code
must correspond to the code appearing next to the fuse holders.
Note: Always check the information printed on the rear of the
detector for the most up-to-date details regarding the fuse type.
For details on checking and replacing fuses see Electronics
section.
3.17 Power Up
After connecting the detector to AC power, press l on the power
rocker switch. The detector will switch on and execute its start-
up routine.
If your instrument fails to power up when the power switch is
turned on, check that the power cord is properly connected, that
the fuses are ok and that there is power at the wall receptacle.
Please refer to the Electronics section of this manual for details
on the initialization routine.
3.18 Front Panel LEDs
The front panel has 3 dual colour LEDs that indicate the
detector’s status during its stages of initialisation and operation.
The color coding for each one is defined in the table below.
