DYNAMINI TEMPERATURE CONTROLLER SET-UP
Temperature Control Functions in General
The Dynamini temperature controller provides accurate temperature control for the hopper, hoses
and applicators. Setpoints are programmed at the user-friendly, all-icon keypad. The controller will
display an error message any time an open or shorted sensor condition occurs.
Defining Dynamini Temperature Control Terms
Adhesive Temperature Control Range
The temperature limits within which the ASU, hoses and applicators may be programmed and main-
tained.
Printed Circuit Board (PCB)
The Dynamini contains one pcb. It contains the central processing unit (CPU) of the microprocessor
temperature control as well as providing control signals to, and monitoring signals from, the hopper,
hoses and applicators. It features lighted LEDs to indicate that heater power is ON. The ASU’s fuses
are located on this board.
Dynamini Temperature Controller
The built-in control system that controls, monitors and displays all system temperature values of the
Dynamini adhesive application system.
Mechanical High-Temperature Protection
A mechanical, redundant thermostat located on the hopper that will turn off the system above 232
°
C
(450
°
F).
RTD Sensors
The Dynamini system uses 100-ohm platinum resistance temperature detector sensors for all temper-
ature controls.
Sequential Startup
This feature allows the temperature zones to come on in sequence (hopper, followed by hose, fol-
lowed by head). When activated, and the ASU is turned ON from a cold start, the hopper heats first.
When the hopper is within the programmable tolerance of setpoint, the Head(s) and hose(s) begin to
heat. No other features of the ASU are affected by sequential startup.
Note: sequential startup is rarely used. In most cases, it should be de-activated to ensure rapid warm
up.
