SET-UP
HEAT BLOCKING INSTALLATION
1. Carefully remove Heating Block and Temperature Controller from packaging inside shipping box. Place the
Heating Block on a working surface that is clear of heat sensitive items, such as paper or equipment, or heat
conducting material. The Temperature Controller can be placed next to the Heat Block or up to 6 feet away
with Connector Cable.
2.
Important Note:
Make sure to use Heating Block and PID Controller that have matching serial number (S/N).
Once a Heating Block is calibrated using the PID Controller, this is important for maintaining that calibration.
If Heating Block and Temperature Controller are mismatched, calibration must be carried out again. Heating
Block serial number is found by turning over the block while the serial number for the Temperature Controller
in on a label on its side.
3. The Heating Block Connector Cable, which is attached to the block, has two plugs on the free end for
connecting to the Temperature Controller (refer to Figure 2). Connect the round 3-pin plug of the Connector
Cable into
the receptacle marked “
L
oad” on
the back of the Temperature Controller
as shown in Figure 2. Also
on the back of the Controller, connect the 2-prong plug of the Connector Cable into the receptacle marked
“
S
ensor”.
