3.5.2 NON HEATER-WIRE MODE
If no heater-wire is detected, the MR810 initiates non heater-wire mode. In this mode the heater plate
temperature is controlled to a fixed value. Heater plate temperatures for each temperature setting are as
follows:
Low Setting: 45 °C
Medium Setting: 60 °C
High Setting: 70 °C
As this mode controls to a fixed heater plate temperature, any variation in ambient temperature has no effect
on the control algorithm.
3.6 DIAGNOSTIC PORT

used with the communication cable found in the service kit REF 043042263 to connect to a PC.
