SimpleDist® Micro Heating Block:
Operation & Instruction Manual
Troubleshooting
The problem can be effectively diagnosed by determining if the
controller is or is not getting voltage using the following steps:
1. Confirm that the power cord is plugged securely into the
SimpleDist® Micro heating block receptacle and a working
outlet.
2. Confirm that the switch is in the “on” position. Press button
on the back of unit.
3. Check the fuse located in the power socket:
Warning:
Unplug the unit from the wall power source,
ensure no voltage is present. This procedure is a potential electrical
hazard and should only be performed by qualified personnel.
4. If the controller will not illuminate and the above steps have
passed, the controller is faulty. Call Environmental Express at
+1.800.745.8218 for service.
There are two possible causes for your heating block to sound
the alarm immediately after the controller cycles through the
self test.
1. Your set point has been set to a value (≥) 15° less than ambient
or current set point temperature. Turn the set point to within
15° of the actual temperature (blue numbers).
2. The controller is faulty. Call Environmental Express at
+1.800.745.8218 for more information.
