4.2 Liquid Injection Valve
Temperature Control
The Siemens Liquid Injection Valve Heater Module probe is connected to a Base Detector
Personality Module (DPM) Temperature Controller. Most Base DPM boards have two
temperature control circuits so there is normally an extra one for the SLIV. If not, then a
Temperature Control Module (TCM), part number A5E02645925002, is added to the analyzer.
One of the Low Wattage relay pairs on the PECM is used to control the SLIV heater. A cable
from the DPM to the PECM is used to control the low wattage relay on the PECM. This cable
is not shown in this diagram.
