3.9 Troubleshooting the ATR19’s internal mains power supply
This chapter shall assist you in fixing problems with the ATR19 (not ATR19-2) internal mains supply, which is very similar to
the SPS1. It describes procedures to verify the internal power supply and how to change fuses in case of problems. A problem
with the internal power supply is indicated if some of the green LED in the front panel are not lid or the voltages in the front
panel test points are not between 5.5 and 6.5V, both polarities. A FAQ (Frequently Asked Questions) list on the ATR19 and
its functions is continuously updated. Please refer to our WEB site for updates of this manual.
1) Turn on the ATR19. Check if the green power switch is lit (the switch illumination might be very dim if the ATR19
is operated with 100-115 VAC).
If not: check the power connection. Check the fuse at the back panel of the ATR19 (fuse holder is integrated into the
mains plug socket, see picture below) and replace when necessary. Only use fuses of the following readings:
250V 630mAT when operated at 100 VAC
250V 500mAT when operated at 115 VAC
250V 315mAT when operated at 200 VAC
250V 250mAT when operated at 230 VAC
(T = (German:) träge = slow blow = time lag)

If the problem persists please follow steps 2) to 9).
