Series 8 Controllers
Temperature and High Limit Controller
The Series 8 is SSi’s affordable line of process and high limit controllers. These products are used for many thermal processing and indicating applications. The Series 8 has universal inputs with relays and analog outputs allowing for versatility and a wide range of monitoring or controlling applications. With 3 options for sizes (1/16, 1/8 and ¼ DIN), the panel mount unit offers high accuracy universal inputs for PID control and high limit protection.

See our Schematics and Drawings Page for wiring info.
See our Instrument Setup Sheets Page for information on your device.
If the alarm is supplied or configured as a latching type, it can be acknowledged in Level 1 or Level 2.
Press Page, F1, or F2. The controller will display “Ac.AL” (for Alarm Acknowledge).
Use the Up and Down buttons to select YES, then press the Scroll button to accept.
NOTE: If the alarm is still present, the ALM beacon will light continuously and the alarm message will continue to flash.
NOTE: By default, the Page button is configured to Ac.AL.
First, enter the Level 2 Menu as follows:
Press and hold Page until the screen displays “Goto”
Press Up until the screen displays “Lev 2”
Press Scroll to enter the Level 2 Menu.
Then, enter the passcode if necessary as follows:
Press Up or Down until the screen displays the correct passcode.
Press Scroll.
The controller is now operating at Level 2.
Enter the offset as follows:
Press Scroll to scroll through options until the screen displays “oFS”
Use Up and Down to select the +/- offset amount needed.
Press Scroll to advance. The value will be stored in the controller when you exit the oFS screen.
