There are three types that each relay, individually, can be set to, for
example, consider Relay 1, you can select parameter P210 from the
following options:
0 = Not in Use relay will remain in the de-energised condition.
1=Alarm: relay will de-energise to set the alarm “ON”.
2=Control relay will energise to set the control “ON”.
Alarm Relay Set-up
The alarm relays are de-energised to turn the alarms “ON”, and energised to
turn the alarms “OFF”. In this way, loss of power will ensure that the alarm
is activated.
To set an alarm relay, set the first parameter for the relay to equal 1
E.g. Setting Relay 1 for alarm purposes P210 = 1
Setting Relay 2 for alarm purposes P220 = 1
The second parameter for each relay determines the function of the alarm
relay, using the example of Relay 1, the alarm function can be selected
from the options available in parameter P211.
For full details of all available alarm options please refer to P211, 221 Relay
Function… If P210, 220 = 1(Alarm) tables in Chapter 5.
The third parameter, and the fourth parameter for each relay set the
Alarm “ON” and “OFF” points. For a high alarm then set “ON” higher
than “OFF”. For low alarm then set “ON” lower than “OFF”. Using the
example of Relay 1 P213 and P214 set the “ON” and “OFF” points.
For example using Relay 1
High Alarm
