<p><font color="#0080FF" size="6">Principles of Operation</font></p>
<p>The <strong>DM3000 Brake Monitor</strong> system
components are: a <strong>control unit</strong> and a <strong>motion
detector</strong> (standard with 10' cable - other lengths
available upon request).</p>
<p>The control unit interfaces electrically with the motion
detector, by means of a motion detector cable. The motion
detector is mechanically connected to the crankshaft of the press
by chain, belt or direct drive and generates an electrical signal
whenever there is shaft movement.</p>
<p>The brake solenoid voltage (which is removed to apply the
brake on the press) is constantly monitored by the control unit.
When the voltage is removed, a high precision digital counter is
activated, which continues to count until the motion detector
signal indicates all motion has ceased. The elapsed time is
indicated on a 3-digit LED display on the face of the control
unit.</p>
<p>The <strong>Brake Monitor</strong> opens the control
relay in the Stop Output circuit, whenever the stop time of the press
exceeds the preset limit - the Stop Output must be wired in a way that prevents a
successive stroke of the press. The Stop Output also features a <strong>safety
relay</strong> with its contacts wired in series with
those of the control relay. This safety relay works in
conjunction with an armature configuration in the control relay,
which allows for the detection of a welded relay contact, and
opens the Stop Output if a contact weld occurs. A separate,
adjustable <strong>Warning Output</strong> provides
a means to alert personnel to the fact that stop times are
approaching the alarm point - this feature warns of brake
wear and helps to eliminate unintended machine stops.</p>
<p>The combination of a <b>key lock</b> and <strong>keypad</strong> allows the authorized
user to alter the alarm, warning and chain-break delay settings and
to control whether the unit displays stop or reserve times.
The key lock enables the keypad access. An
<strong style="font-weight: 400">access code</strong> prevents unauthorized
keypad entry. </p>
<p>A <strong>self-check circuit</strong> monitors the
control. It operates continuously and is independent of
machine cycle. In the event of a self-check fault, the
Stop Output opens and a fault code is displayed on
the 3-digit LED. A <strong>chain-break detection circuit</strong>
monitors the motion detector input and alarms the unit if the
motion detector is either disconnected or fails to provide a
signal.</p>
