"handshake" signal between the autocali-
bration system (SPS 4000 or IMPS 4000)
and is unavailable for alarming purposes.
The following additional contacts are pro-
vided through the autocalibration systems:
1. SPS 4000 and IMPS 4000, 1-4
probes.
(a) One contact closure per probe
from the control room to the SPS
4000 or IMPS 4000 for "calibration
initiate".
(b) One contact output per probe from
SPS 4000 or IMPS 4000 to the
control room for "in calibration" no-
tification.
(c) Once contact output per probe
from the SPS 4000 or IMPS 4000
to the control room for "calibration
failed" notification. (Includes output
from pressure switch indicating "cal
gas bottles empty".)

IDENTIFYING AND CORRECTING ALARM
INDICATIONS
Faults in the Oxymitter 5000 are indicated using
the four diagnostic, or unit, alarms. The pattern
of repeating blinks will define the problem. A
condensed table of the errors and the corre-
sponding blink codes can be found on the inside
right cover of the electronics housing. Table 5-1
also identifies the blink code and fault status of
each LED as well as the output of the fieldbus
digital signal line and a fault number that corre-
sponds to the troubleshooting instructions pro-
vided in this section.
