Relay 17, 18 and 19 together with the Auxiliary Relays (if fitted) may be programmed to any one of the following options:
--- Relay not programmed.
STREAM Output set for stream valves 1-6.
STM ALARM Stream alarm relay 1-6.
MANUAL Output set for Manual Valves 1-6.
FAULT (Normally energized output) set to operate on fault condition.
WARNING (Normally energized output) set to operate on warning condition.
FAULT OR WARN (Normally energized output) set to operate on fault or warning conditions.
NOTE (Normally energized output) activated when a notification is logged in the fault archive.
STOP Output set to operate when the BioTector is stopped condition. Note that remote stand-
by is not considered as a stop condition.
MAINT SIGNAL Output when MAINTENANCE SWITCH (input 22 by default) is activated.
CAL SIGNAL Output set to operate on Zero/Span Check and Zero/Span Calibration reactions.
CAL Calibration Valve used during calibration reactions.
ALARM Alarm relay, activated upon programmed alarm conditions.
SYNC Synchronization relay, use to synchronize the system with external control units.
MAN MODE TRIG Indicates that manual reactions are activated and going to be executed regardless of
the activation is carried out manually on the keyboard or remotely from Input 7 by
default.
4-20mA CHNG 4-20mA output change flag relay, which is always activated for a period of 10s, when a
new result causes update of any of the 4-20mA output channels.
4-20mA CHNG 1-6 4-20mA output change flag relay, which is always activated for a period of 10s, when a
new result causes update of a given 4-20mA output channel for a specific stream.
4-20mA READ This signal is used to indicate valid/stable values on 4-20mA output channels in 4-
20mA Stream & Full Multiplex operation modes.
SAMPLER FILL Fill signal, sent to the sampler, which remains on from start of sampler fill time to the
completion of the sample injection.
SAMPLER EMPTY Empty signal, sent to the sampler, which is a pulse of 5 seconds duration and is
triggered after the Sample Pump reverse operation is complete.
SAMPLE STATUS Digital output activated (energized) when BioTector Sample Sensor detects no sample
or when the sample quality is less than the default 75% threshold value (i.e. when
there is significant quantity of air bubbles in the stream/manual grab sample lines).
SAMPLE FAULT 1 Output when the external SAMPLE FAULT 1 input signal is activated.
