When uncertain as to the cause of the failure, have a qualified electrician check the
line voltage for transient and/or drop-outs at the receptacle.
If the alarm persists,

It indicates that there has been an interruption of power to the instrument. This can
occur due to a loss of power in the user’s laboratory or merely due to switching the
instrument off and then back on. It does not necessarily indicate that there has been
a “black out” at your location. If the ATP™ has lost power during a process, its
automatic power outage protection will allow it to carry on from where it had been
interrupted. How it will do so depends upon what station was active when the power
outage occurred, according to the following:
a) Steps 1 to 10 (reagents): No special action, the black-out time is considered
processing time and the ATP™ continues as if nothing had happened.
b) Steps 11 - 12 (paraffin): Processing will pause (for approximately as much time
as the unit was without power) for the Retort and paraffin containers to return to
the proper temperature. The blackout time and the related heating time are NOT
considered processing time.
Cause – Loss of power in the lab, a blown instrument fuse, or merely switching
the unit off or jarring the power cord out of the wall or out of the instrument.
Solution – If the power supply doesn’t return, check the electric network, plug
and cable. If necessary, replace the instrument fuses as described in Chapter 14.
The alarm will be displayed on the screen until the cause is removed. If the
instrument is found working (after a black-out), but, this alarm appears too
frequently (e.g. more than once in a month), it would be prudent to have the unit
connected to its own power supply (separate circuit and breaker). As a separate
issue, uninterruptible power supplies (UPSes) may be utilized to protect against
power fluctuations and spikes; but, even larger UPSes will provide only a few
minutes of electricity for instruments like the ATP™ that consume a large amount
of current.
CAUTION: All laboratory tissue processors rely on the fact that
power outages at hospitals, clinics and industrial facilities will be of a short
duration (less than one entire process step), as they should have adequate
backup generators, etc. No tissue processor can protect samples totally from
long delays, especially in dehydrant steps. If you anticipate an extended power
outage, take steps to protect your tissue samples or the processing quality could
be compromised.
