2. When coolant temperature is greater than 62 °C (144 °F), a trip signal is
initiated. It can only be reset when the temperature reaches 48 °C (120 °F).
3. When coolant temperature is less than 4 °C (40 °F), a trip signal is
initiated. It can only be reset when the temperature reaches 10 °C (50 °F).
De-Ionizing Cartridge and Mesh Filter
The flow circuits shown in Figure 284 filters and de-ionizes coolant at a rate of
about 19 L/minute (5 gpm). Valve V14 may be closed only if the coolant mixture
in the drive has a freeze temperature colder than -40 °C. This allows a decreased
flow to 5.3 L/minute (1.4 gpm)
This stream can be isolated for cleaning and maintenance by closing the incoming
valve V8. The filter is a 500-micron fine-mesh type, which can be cleaned many
times by rinsing in clean water. The de-ionizing cartridge is a mixed-bed cartridge
type, which can be disassembled easily for de-ionizing cartridge replacement.
