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. For
example:
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:
