Defining DynaControl Temperature Control Terms
SSRs & Aux Power Modules
The SSRs and V6 Aux Power Module provide power to all the temperature zones in the
ASU’s system. The platen power is controlled via SSRs and hoses and applicators are
controlled by the Aux Power Module.
V6 Base Module
The main control module of the system. It controls and communicates with the
temperature control module, the operator interface and all auxiliary modules and I/O
devices.
V6 Temperature Module
Monitors temperature signals from all heated zones and provides control signals to the
SSRs and Auxiliary PCBs (modules).
Default Settings
The factory-set programmable system values that will be in effect if the user does not
enter new values.
Temperature Control Range
The temperature limits within which the ASU (Adhesive Supply Unit), hoses and
applicators may be programmed and maintained.
Ready Temperature
The programmable temperature which allows the ASU pump to turn ON. The default
ready temperature range is a deviation 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.
Set points
The temperatures that you have selected and programmed for each of the temperature
zones.
Set point Limitation
This is a universal maximum temperature for all zones. The programmer cannot program
a temperature set point higher than the set point limitation. If the actual temperature of
any zone climbs higher than the set point limitation, all heaters will shut down.
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.
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 rapid system warm-up when run
condition is selected. When standby mode is activated, the controller will display
STANDBY.
Error Indication Alarms
Controller alarms which indicate that the programmed over-temperature values have
been exceeded for one or more platen, hose or head zones or that a zone temperature
has fallen beneath its hi-lo tolerance. Alarms may also indicate an open or short-circuited
sensor.
