Crompton Controls M20 - Manual (Page 9)

8 Getting Started Emotron AB 01-2551-01r4
4.3 First start
1. Start the motor/machine and let it run at normal load, until the Start Delay
has expired.
2. Press for 3 seconds.
Hint!
Short-circuit the output relays during the set-up; this prevents the equipment
from stopping unintentionally.
More Hints!
The monitor can be set in three different ways:
1. Automatically by pressing the Auto set key as described above. The Auto set
function performs a measurement (momentarily) of the actual load and sets
relevant alarm levels for this actual load plus/minus the “margins” (Default;
Max +16% and Min -16%).
2. If Auto set is used as above, the margins can be re-adjusted manually (win-
dows 21-24). When the margin values are changed a new Auto set must
always be performed to activate the changes and the new margins. More
information is provided in chapter 9, Advanced Features.
3. Manual setting of alarm levels (windows 11-14). The alarm levels can be set
manually, without using the Auto set. See sections Manual setting of alarm
levels, alternative A, B and C.
CAUTION: Make sure that all safety measures have been taken before
switching on the supply voltage and starting the motor/machine in order to
avoid personal injury.
NOTE: If any window parameter is manually adjusted, the display will flash
the new value to indicate that a change has been made. The Enter key must
be pressed for the M20 to accept this new value.
