and properly grounded.
Always disconnect power to the instrument before
opening the enclosure or making any wiring changes.

Caution: Additionally, this device is intended to control heaters and
thermal systems, which may be hot and/or dangerous.
Beware that damage to heaters and other equipment,
possibly resulting in personal injury or death may result
from improper use or control of thermal systems.

Understand the safety implications of your system and
take proper precautions to avoid damage to property or
injury to personnel.

Overview

Model 101303-23

Overview

The HeatWave Labs Model 101303-23 is a full featured, high quality rackmount
temperature controller designed for low-voltage tungsten heater control applications
requiring precise, reliable control and ramp/soak programmability.

Over-temperature protection is provided by a completely independent limit
controller and sensor. The alarm will disable power to the heater if the alarm
setpoint is exceeded. Alarm switching is provided by an independent, internal
mechanical relay in series with the solid-state control relay. This alarm scheme
provides protection against system runaway if the solid-state relay should fail in the
closed position. In addition to over-temperature protection, the Model 101303-23
provides other mechanisms like open loop and open sensor detection to assist in
system protection. The phase-angle fired SCR is protected by a semiconductor fuse
that can be replaced via back-panel access.

Control Module Displays and Menu Navigation

The Watlow® Series 96 Controller with the ramping software option allows
programming of 2 temperature vs. time profiles (called files) that can each have up
to eight distinct steps programmed into them. Upon power-up, the unit starts at the
Home Page and indicates the process temperature in the upper display and the
setpoint (or
) in the lower display. While not running a profile, the setpoint
can be directly adjusted with the up and down arrow keys. The setpoint is registered
about 2 seconds after the last pressing of either up or down arrow.
Management, programming, and execution of temperature vs. time profiles are
explained in the Programming and Executing Profiles section.
































Figure 1 Control module keys and displays
LEDs 1 to 4:
1. Illuminated when heater output is active. For example, it will be
on continuously when the heater is at 100% power, and on half
the time when the heater is at 50% power.
2. Not used.
3. Illuminated when the over-temperature alarm has been activated.
4.
Not used.
Advance Key:
When at the home page, pressing this
key will open the programming menu.
If in other menus, this key selects the
menu choice in the upper display,
scrolls through menu selections, or
will scroll through parameter values in
the lower display.

Infinity/Home Key:
From the home page, pressing once opens
the Pre-run menu; pressing again starts
the profile and opens the Run menu.
If not at the home page, pressing this key
will exit the menu system and return to the
home page.

Up and Down Keys:
Pressing up or down alone
changes the setpoint or
parameter value.
Pressing them
simultaneously for 3 seconds
accesses Operations Page.
If held for 3 more seconds,
accesses Setup Page. See
Watlow Series 96 Users
Manual for full description of
Operations and Setup Pages.

Upper Display:
Indicates process
temperature, or
parameter value
when in menus.

Lower Display:
Indicates process
setpoint, or
parameter name
when in menus.
Profile Indicator:
Illuminated when controller
has been set to manual
mode, where Upper Display
indicates percent output.
