Features
Temperature control is achieved with the Partlow Model 1160+
Controller. The 1160+ is a non-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
Selectable pre-tune, self-tune, manual tune
1 Universal Input: Type J Thermocouple
1 Control Output: 0 - 10 VDC Time Proportioned
2 Alarm Outputs: Triac and Relay
Communications: Optional for RS-485 w/ Modbus
Displays and Keys:
The front panel of the Partlow 1160+ is provided with user-friendly features that aid in monitoring and setup.
The upper display indicates actual process values while the lower display indicates setpoint value. The
following LED indicating functions are employed.
MAN: On Steady – Indicates the Setup Mode has been entered
Flashing – Indicates the Manual Mode has been entered
AT:
On Steady – Indicates the Controller Self Tune Mode is engaged
Flashing – Indicates the Controller Pre-Tune Mode is engaged
ALM: Flashing – Indicates an alarm condition is present
LED: On Steady – Primary power is >0%
Flashes in unison with Time Proportioning Primary outputs, or for Current Proportioned outputs
LED: On Steady – Primary power is >0%
Flashes in unison with Time Proportioning Secondary outputs, or for Current Proportioned
outputs
Raise and Lower Keys are provided, along with an Auto / Man Key. The Function Key (Circle Arrow) is used
to navigate between modes and parameters.
Data Communications:
As an option, RS-485 serial data communications may be provided with user-selectable Modbus protocol, or
ASC II protocol (in some models). An RS-485 Communications Module is fitted in Option Slot A with this
feature. 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.
