Two-Hand-Control-Buttons (Left & Right-Confirm-Buttons)
The platen will not move until the two-hand (mechanical) buttons are depressed
simultaneously. This prevents the operator from placing one or more of their own hands
and/or arms at the pinch point between the platen and the drum of adhesive.
See Chapter 5.2 Setting-up operation.
System Status Lights
The stack lights ease remote monitoring of the system’s
status. They are mounted on top of the panel box
assembly.
• On t
he tri-color stack light, the lower, green light
illuminates when the system has warmed up to
temperature setpoints.
• The middle, amber light illuminates when the level of
material in the drum is low. This is the operator’s
signal that a fresh drum of adhesive will soon be
needed.
• The upper, red light illuminates when the drum is
empty or there is an alarm condition and is
accompanied by an audible alarm.
• The horn is housed within the upper (black) section of
the stack.
Mechanical High-Temperature Protection
The Bulk Melter includes a mechanical (redundant) over-temperature thermostat that acts
as a safety backup. If the unit’s manifold temperature should exceed 232°C (450°F), the
thermostat will cause the Melter’s circuit breaker to open and power to the manifold,
platen, valve heater and hose(s) will be cut off. The mechanical thermostat automatically
re-sets after the manifold temperature falls below 204°C (400°F).
RTD Sensors
The standard Dynamelt system uses 100-ohm platinum resistance temperature detector
sensors for all temperature controls.
