1.1 MAIN FUNCTION:
The MICROCOM
®
temperature controller is
designed to control hot runner systems.
1.2 CONTROLLER SPECIFICATIONS:
• INPUT POWER: 230 VAC single phase.
• INPUT POWER RANGE: 207 VAC to 253 VAC.
• MAXIMUM OUTPUT POWER: 3600W.
(15 Amps).
• FREQUENCY: 60Hz / 50Hz.
A label is affixed to the cabinet indicating:
1.3 TECHNICAL FEATURES:
1.3.1 TEMPERATURE MEASUREMENT:
• Thermocouple type J (“J” display) or type K
(“nI” display), grounded or ungrounded, with
automatic cold junction compensation
(selection of the thermocouple in the
configuration menu).
• Sampling rate, 83 ms @ 60 Hz or 10 ms @ 50Hz.
• Ac/- 0.5% over the range 32 to 932 °F
(0 - 500°C).
• °F or °C scale (user select in the
configuration menu).
• Reversed thermocouple detection (no power to
the heater, 0% output).
• Broken Thermocouple detection automatically
switches to manual mode by applying the
last stored percentage of power to the heater
(adjustable through software).
• High and Low alarm.
1.3.2 TEMPERATURE CONTROL:
There are 2 control modes :
AUTOMATIC MODE (closed loop):
This is a self-tuning PID control unit. The controller
continuously monitors the behavior of the heater
which it is connected to. The controller adapts its
output to the heater by automatically defining the
P.ID. parameters.
MANUAL MODE (open loop):
In this mode, the controller sends the percentage
of power stored in memory to the manual set
point (default value: 20%). Note that this value can
only be modified in the standby display. When
the controller is in MANUAL mode, high and low
alarms are no longer active. The same is true for
the SoftStart function.
START UP PHASE (“SoftStart phase”):
This phase is designed to avoid cold start failures
and extend the life of the heating element(s). It
eliminates the thermal shock during the transition
from cold to hot.
This phase also removes any moisture that
may have collected in the heating element(s)
by applying low power to the heater or by
progressively increasing power to the heater.
There are 2 types of “SoftStart phases”.
• RAMP DURATION: Heating with maximum
power limited to15% for a 5-minute period or
up to a maximum temperature of 212°F (100°C).
• RAMP RATE: Applying a temperature rate
expressed in °F / min ° (or °C / min ) up to the
user setpoint.
