6.15.3 Moisture protection
When a moisture sensor is installed in series with the
thermal sensor, the control unit needs to know how to
determine whether there is a high temperature or
moisture in the pump. If the temperature is too high,
normally the temperature sensor will go back to its
normal stage when the temperature has dropped to
its trigger level. If there is moisture in the pump, then
the moisture sensor will keep the series connection
open until the pump is opened and serviced.
To determine which sensor has been active, a cool
down time must be entered. This is the time that will
normally pass until the temperature has dropped
enough for the temperature sensor to return to its
normal stage. If the cool down time is exceeded, the
control unit will assume that there is moisture in the
pump, and it will send a moisture alarm.

You can set the current, temperature and moisture
protection via a setup wizard.
1. Go to Settings > Motor protection pump
1 or Motor protection pump 2.
2. Follow the on-screen wizard to set the following:
• Nominal pump current
• Trip IEC class
• Pump connection
• Overheat protection.

during which the overload condition is allowed to exist
within a period of 10 seconds.

A pump is to cut out after 10 seconds because the
rated current has been exceeded.
1. Select trip class.
2. Set the overload limit to 10 A. The rated motor
current is stated on the nameplate.
See position 3, curve with tripping. LC 231 cuts out
the pump because the pump startup time exceeds 10
seconds and the current exceeds 10 A
See position 4, curve without tripping. During pump
startup the starting current only briefly exceeds 10 A
and the pump is not cut out.
Note that the curves are examples and cannot be
used for readings.
Contactor Current Protection (CCP)
In addition to the IEC trip class, a Contactor Current
Protection (CCP) trip class is implemented to protect
the internal contactors in the product from
overheating.
