4.5.1.1.5 Horn On
The Horn On entry allows linking this alarm to the common horn relay. When set to No the alarm has no
effect on the horn relay. Entering Yes causes this alarm to turn the horn relay on steady, or, to pulse it
depending upon horn relay configuration (Chapter 4.3.2.2).
4.5.1.1.6 Color
The Color menu selection gives the option of assigning Alarm 2 and Alarm 3 different colors besides the
default, red. The options are red, blue and orange.
4.5.1.1.7 Enabled
Most applications require only two alarm levels, the default configuration has the Alarm 3 Enabled menu
option set to No. Setting Enabled to Yes activates the Alarm 3 alarm level if needed.
4.5.1.2 Fault Alarm
The Fault Alarm activates when the input is out of range in the negative direction. The fault level is always
low trip and the dedicated common fault relay is always failsafe. The minimum setting is -10% of full scale.
The factory default setting is -10; which is -10% of 100, or default full scale value. If the full scale value is
changed the fault value is automatically updated to reflect the new value. For example, if the fault level
is -10 and the full scale value is changed from 100 to 50 the fault level will automatically change to -5
which is -10% of the new full scale value. If the fault level is -5 (-5% of full scale) and the full scale value is
changed from 100 to 50 the fault level will automatically change to -2.5 which is -5% of the new full scale
value.
