Typical Wiring Diagram (I <
25A)
|
Installation
The E-220 must always be installed on
the input side of any variable speed drive or soft start. The
wiring diagram above is shown as a typical example. Please refer
to the Installation manual for full details.
Relays
Relays on Types 1, 2 and 4 are normally
held closed and open on trip. The warning trip on Type 3 is
NO. Transducer versions, Types 5 and 6, do not have relays.
Other configurations are available. Please consult Autogard.
Programming
The E-220 is programmed using the buttons
on the front panel. The "Mode" button is used to select
the parameter to be programmed and the arrow keys are used to
change values.
Setting Trip Levels
The drive should be operated under normal
load conditions and the displayed power used to determine the
load under normal conditions. The trips should then be programmed
at an appropriate level. Alternatively, a theoretical value
can be determined for the load and the trips set accordingly.
Start Delay
The start delay timer, Ts, is used to
inhibit trips during motor start-up. The shortest possible time
should be selected to maintain optimum protection. The Ts LED
will be lit as long as the start delay is active.
Trip Delay
The trip delay Td inhibits trips until
the limit has been exceeded for the programmed length of time.
This avoids tripping due to noise spikes and transients. It
should be set to the shortest time which does not produce nuisance
trips.
Trip Inhibit
By applying +12-24V DC to terminal IN2,
the trips are inhibited. This input may be provided from a PLC
to inhibit trips during a certain phase of operation or to avoid
unwanted underload trips, for example, on motor shut down. Alternatively,
an auxiliary contact may be used to provide +12-24V to IN2 automatically.
Resetting
Trips may be re-set manually using the
button on the front panel or remotely by applying a +12-24V
DC signal to terminal IN1. |
