SAFETY SUMMARY
All safety related regulations, local codes and instructions that appear in the manual or on equipment must be observed to ensure personal safety and to prevent damage to either the instrument or equipment connected to it. If equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment may be impaired.
Do not use the controller to directly command motors, valves, or other actuators not equipped with safeguards. To do so can be potentially harmful to persons or equipment in the event of a fault to the controller. If redundant safeguards are not in place, an independent and redundant temperature limit indicator with alarm outputs is strongly recommended.
CAUTION: Risk of Danger.
Read complete instructions prior to installation and operation of the unit.
SETTING THE CURRENT INPUT JUMPER
When Input Type is selected as one of the two current input types (0-20 or 4-20), the current input jumper must be installed. The current input jumper is factory set for Temperature and Voltage input types. To change the jumper to configure the input for a current input type, the inside of the unit must be accessed and the jumper position changed.
To access the jumper, locate the two latches located on top and bottom of the front of the unit. Starting with the top latch, insert a small flat-blade screwdriver between the case latch and bezel while using your thumb to push out on the bezel until the latch is disengaged. Repeat this process with the bottom latch. After the latches are disengaged, using the flat-blade screwdriver, gently pry out on the bezel in several areas until the unit releases from the case.
Look for the Current Input Jumper which will be located close to the pc board area that connects to the input terminals. If a current input type is desired, position the jumper across both pins. If input type is anything other than a current input, position the jumper on only one pin.

INSTALLING THE CONTROLLER
The controller is designed to be mounted into an enclosed panel. The unit must be inserted in the case during installation of the controller.
Instructions:
1.Prepare the panel cutout to the proper dimensions.
2.Assemble the mounting clip by inserting the nut into the slot and then insert the screw and thread through the nut as shown (See drawing)
3.Slide the panel gasket over the rear of the controller, seating it against the lip at the front of the case.
4.Insert the controller into the panel cutout. While holding the controller
in place, install the panel latch(es) and then slide it to the farthest |
PANEL LATCH |
forward slot possible. |
(SUPPLIED W/UNIT) |
5.To achieve a proper seal, tighten the panel latch screws evenly until the controller is snug in the panel, torquing the screws to 13.9 to 20.8 oz-in (9.8 to 14.7 N-cm). Overtightening can result in distortion of the
controller, and reduce the effectiveness of the seal.
Note: The installation location of the controller is important. Be sure to |
|
keep it away from heat sources (ovens, furnaces, etc.) and away from |
|
direct contact with caustic vapors, oils, steam, or any other process |

by-products in which exposure may affect proper operation. |
