Alarms
P210, 220, 230, 240, 250 =1 (Alarm)
The second parameter for each relay determines the function of the alarm.
P211, P221, P231. P241, P251 - Relay Function
This parameter defines what function the alarm will respond to as follows.
Option Description
0= Off (Default)
Relay will not operate.
1= Level
Alarm is based on the level in the vessel, and the
type of level alarm (P2
1 2, 2 2 2, 2 3 2, 2 4 2, 2 5 2) and
two setpoints must be set (P2 1 3, 2 2 3, 2 3 3, 2 4 3,
2 5 3 & P2 1 4, 2 2 4, 2 3 4, 2 4 4, 2 5 4). Setpoints are
entered in Display Units or % of span as referenced
to Empty Level
*
.
2= Rate of Change Alarm is based on the rate of change of level in the
vessel, and the type of rate of change alarm (P2
1 2,
2 2 2, 2 3 2, 2 4 2, 2 5 2) and two setpoints must be set
(P2 1 3, 2 2 3, 2 3 3, 2 4 3, 2 5 3 & P2 1 4, 2 2 4, 2 3 4, 2 4 4,
2 5 4). Setpoints are entered in Display Units per
minute or % of span per minute and a negative
value should be entered for a Rate Alarm on a de-
creasing level, and a positive value for an
increasing level.
3= Temperature Alarm is based on the temperature, and the type of
temperature alarm (P2
1 2, 2 2 2, 2 3 2, 2 4 2, 2 5 2) and
two setpoints must be set (P2 1 3, 2 2 3, 2 3 3, 2 4 3,
2 5 3 & P2 1 4, 2 2 4, 2 3 4, 2 4 4, 2 5 4). The temperature
used depends on the temperature source selected
(P852). Setpoints are entered in
o
C.
4= Loss of Echo Alarm is raised if the Failsafe Timer ( P809 )
expires. No setpoints are required.
5= Loss of Clock
Alarm is raised if the real time clock fails. No
setpoints are required.
When Ultra Wizard =2 Pump Differential
and Pump Efficiency Enabled
6= Pump Efficiency
When Pump Efficiency is enabled, Alarm is
based on the Efficiency of the pump which is
allocated to the relay I.D. (P2
1 2, 2 2 2, 2 3 2, 2 4 2,
2 5 2) and two setpoints must be set (P2 1 3, 2 2 3,
2 3 3, 2 4 3, 2 5 3 & P2 1 4, 2 2 4, 2 3 4, 2 4 4, 2 5 4).
Setpoints are entered in %.
