Over-Temperature Setpoint
The programmable temperatures that will cause alarms to occur when those temperatures
are exceeded. Power is not disconnected, the READY contact opens and the alarm contact opens. If
an external alarm has been connected, it will activate. The over-temp setpoint is the upper limit of
the ready temperature range of each zone.
RTD Sensors
The standard Dynamelt system uses 100-ohm platinum resistance temperature detector sensors for
all temperature controls. Ni120 is available as an option.
Ready Temperature
The programmable temperature which allows the ASU pump to turn ON. The default ready temper-
ature range is a deviation of + 20C(+36F) from the setpoint. The setpoint minus the deviation is
the low limit of the range, and the setpoint plus the deviation is the high limit of the range.
Sequential Heating
The heating sequence which allows the slower-heating hopper to reach operating temperature
without unnecessary use of electricity for faster-heating hoses and applicators. Sequential heating is
the time period during which the hoses and applicators remain OFF while the hopper (and optional
drop-in grid) heats up. Hoses and applicators may be independently programmed. If hopper temper-
ature is above ready temperature when the ASU is turned ON, t he hose and applicator sequence is
bypassed and they will be turned ON. Sequential heating is restored after Standby is turned from
ON to OFF S equential heating is not needed for most applications and can delay total system
warm-up time.
Setpoints
The temperatures that you have selected and programmed for each of the temperature zones.
Setpoint Limitation
This is a universal maximum temperature for all zones. The programmer cannot program a temper-
ature setpoint higher than the setpoint limitation. If the actual t emperature of any zone climbs higher
than the setpoint limitation, all heaters will shut down.
Standby Condition
The system condition where the ASU, hose and head temperatures are maintained at predetermined
reduced temperature values. Standby temperatures are set lower than setpoint temperatures in order
to reduce adhesive degradation and energy consumption when the system is temporarily inactive,
and to permit r apid system warm-up when run condition is selected. When standby mode is activ-
ated, the controller will display STANDBY.
