Bulletin 900-TC

Installation

Bulletin 900-TC8

Panel Mounting

1. Insert the Bulletin 900-TC8 into the mounting hole in the panel
    from the front (panel thickness:1 to 8 mm). Ensure the waterproof gasket is in place if this is a
    UL Type 4X enclosure.
2. Push the mounting bracket along the Bulletin 900-TC8 body from
    the rear terminals up to the panel, and secure it temporarily.
3. Tighten the screws on each mounting bracket alternately until the
    ratchet stops tightening.

Bulletin 900-TC8

Removing the Unit from its Case

1. Insert a flat blade screwdriver into the two tool insertion holes (one on the top and one on the bottom) to release the hooks.

2. Insert the flat blade screwdriver in the gap between the front panel and rear case (two on the top and two on the bottom),and use it to pry and pull out the front panel slightly. Then, pull out on the front panel gripping both sides. Be sure not to impose excessive force on the panel.

3. When inserting the body of the Temperature Controller into the case, make sure the printed circuit boards are parallel to each other, make sure that the sealing rubber is in place, and press the 900-TC8 toward the rear case until it snaps into position. While pressing the 900-TC8 into place, press down on the hooks on the top and bottom surfaces of the rear case so that the hooks securely lock in place. Make sure that electronic components do not come into contact with the case.



Bulletin 900-TC16

Panel Mounting



Mounting the Bulletin 900-TC16 in a Panel/Enclosure

1. Insert the Bulletin 900-TC16 into the mounting hole in the panel (panel thickness:1 to 8 mm).

2. Ensure the waterproof gasket is in place if this is a IP66 UL Type 4X

3. Push the panel adapter along the Bulletin 900-TC16 body from the rear terminals up to the panel, and secure it temporarily.

4. Tighten the two screws on the adapter. When tightening the two screws, tighten them alternately, keeping the torque to 0.29...0.39 N•m (2.57…3.45 lb•in).

Attaching the Safety Terminal Cover

Make sure that the UP arrow mark is facing up, and then fit the terminal cover into the holes on the top and bottom of the controller. All Bulletin 900-TC16 controllers are provided with a terminal cover.

Installing the Option Units

If communications, event input, or heater burnout functions are required, mount the applicable option unit into the controller. The heater burnout function is supported on either the 900-TC16EIM or 900-TC16COM units. One option unit (max.) per controller.

Assembly Directions



1. Insert the tools (see drawing above) into the slots (one on the top and one on the bottom) and release the case hooks

2. Insert the tool in the space between the front and rear case selections and slightly pull out the front case. Hold the top and bottom of the front case and pull it toward yourself to remove it.

3. Mount the option unit in the center position. Match the upper and lower option unit (board) retaining claws with the connection points and insert/lock the option unit in place.

4. Before inserting the unit into the panel/enclosure, confirm that the waterproof gasket is in place. Insert the front case into the rear case until you hear a click. When inserting the front case, press down the hooks on the top and bottom of the rear case so that they firmly hook together. Make sure that electronic parts do not come in contact with the case.

Bulletin 900-TC32

Panel Mounting

Note: For waterproof mounting, waterproof packing must be installed on the controller. Waterproofing is not possible when group mounting several controllers. Waterproof packing is not necessary when there is no need for the waterproofing function.

1. For waterproof mounting: Install waterproof packing on the controller.

2. Insert the 900-TC32 into the mounting hole in the panel.

3. Push the adapter from the terminals up to the panel, and temporarily fasten the 900-TC32

4. Tighten the two fastening screws on the adapter. Alternately tighten the two screws little by little to maintain a balance. Tighten the screws to a torque of 0.29...0.39 N·m.



Removing and Attaching the Wiring Terminal Cover Plate

A damaged Bulletin 900-TC32 can quickly be replaced by removing the field terminal plate.

1.Insert a flat-blade screwdriver into the tool holes (one on the top and

one on the bottom) to release the hooks. Do not apply excessive force.



2. Pull the terminal block out while the hooks are released.

Peripheral Devices

Temperature Controller Connection to a Solid-State Relay (SSR)

The 12V DC output of a temperature controller is typically used to interface to an SSR, such as the Allen-Bradley Bulletin 700-Sx line. An SSR provides high current (e.g., 40 A) switching capability plus longer life than a mechanical relay. See the Relays and Timers Selection Guide (Publication 700-SG003x-EN-P) for additional information.

Bulletin 700-SX

Controller Configuration from Keypad

Controller configuration of parameters can be done using the four keys on the bottom of the controller along with the two LED displays. The configuration system is structured, which means a set path must be followed to get from one parameter to another.
User manuals, which provide details about configuring the Bulletin 900-TCx controllers, are available on-line at the Literature Library web site:
