10.8 Auxiliary Alarm Inputs
For additional safety, it is possible to retain the site’s existing float type level controls by using auxiliary alarm
inputs. The schematic below shows an example of how to wire such alarm inputs.
Figure 10.7.i Wiring Auxiliary Alarm Inputs
Note: If any of the three alarms are not being used when an auxiliary alarm inputs have been enabled, a line
voltage input should be connected to the corresponding terminals to stop a fault occurring.
The table below shows the expansion options to be set on the MM for the auxiliary alarm inputs.
Water level control function
Note: Auxiliary alarm inputs can only be used in conjunction with an analogue sensing device such as two
capacitance probes or one capacitance and an external level sensor at minimum. please see section 3.4 for
Ways of Level Sensing for more information.
