9.1 Controller
Features
Temperature control may be achieved with the alternate Partlow Model
1166 Controller. The 1166 is a profiling type, 1/16 DIN controller with the
following main features. The Type J thermocouple used for temperature
sensing is placed in the airflow at the top of the workspace.
Single
Channel
Auto/ Manual Control
1 Universal Input: Type J Thermocouple
Programs: Four with up to 16 free-form steps in each
1 Control Output: 0 - 10 VDC Time Proportioned
2 Alarm Outputs: Triac and Relay
Communications: Optional for RS-485 w/ Modbus / RTU
Data Communications:
As an option, RS-485 serial data communications may be provided with Modbus / RTU protocol. RS-485
type communications is briefly described below.
RS-485: This interface uses only 2 wires. Both wires are used for transmitting and receiving data, and
therefore, only one device may talk at a time. Up to 10 chambers may be connected to your computer on a
multi-drop network up to 4,000 feet long. Data signals are measured as a plus or minus 5 Volt differential.
9.2 Temperature
Control
Temperature control with the Partlow 1166 is achieved with a 0 - 10 VDC time proportioned output. Output 1
will energize a solid state relay, which provides power to the heater stack. The heater must be enabled by
the output of the Overtemperature Controller.

Controller Parameter Setup
The pre-programmed controller configuration for your oven is documented in the Controller Parameter Setup
Chart, which is part of your Test Report. This is located in the Supplemental Instructions Section.
Important!
The configuration set-up is mainly provided for your reference. Not all of the
parameters shown apply to your chamber. Changes to some of the set-up parameters may
drastically affect your chamber performance and void your warranty. Contact the TPS Service
Dept. before attempting any changes.
