1.4 ALARMS
Control Alarms:
2 SPST relays, contacts rated at 5
amps, 240 VAC with a resistive load. May be set as
normally open or normally closed. Alarms can be
configured HIGH/HIGH, HIGH/LOW, LOW/LOW, or
LOW/HIGH. Alarm deadband is adjustable over full
range.
Error Alarm:
SPST relay, used to indicate an instrument
or sensor error.
•
2.0A @ 30VDC or 60VAC ±10%.
•
1.0A @ 60VDC or 120VAC ±10%
•
0.5A @ 120VDC or 240VAC ±10%
(All resistive loads)
Range Alarm
: 1 SPST relay, used to indicate current
output range; contacts open when on Low range and
closed on High range.
•
2.0A @ 30VDC ±10%.
•
1.0A @ 60 VDC or 120VAC ±10%.
•
0.5A @ 120VAC or 240VAC ± 10%.

Dual Alarms
Dual Alarms are standard on the Solu Cube. The set-
point for each alarm is independently adjustable over
the full range of measurement. The relays operate either
as high or low alarms and may be set as either normally
open or normally closed. The alarm conditions are dis-
played on the analyzer as Alarm 1 and Alarm 2 and
may be configured as HIGH/LOW, HIGH/HIGH.
LOW/HIGH, or LOW/LOW.
In addition, two low level alarms are available. One may
be used for Autoranging (see standard Output) and the
other as an error alarm.
