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.
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 screw on each mounting bracket alternately until the
ratchet stops tightening.
1. Insert the Bulletin 900-TC16 into the mounting hole in the panel
(panel thickness:1 to 8 mm).
Ensure the waterproof gasket is in place if this is a IP66 UL Type
4X enclosure.
2. Push the panel adapter along the Bulletin 900-TC16 body from
the rear terminals up to the panel, and secure it temporarily.
3. 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).
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.
