NOTE: User documentation may be available in French, German, Spanish, Italian, and Dutch, as well as English. Check Watlow’s website
(www.watlow.com/) for availability.
NOTE: See semiconductor fuses and holders on pages 2.1 and 3.6.
IMPORTANT NOTES:
Phase Angle:
Phase angle and phase
angle with current limit
are available on single
phase, and 3 phase/3-leg
models only. To get
current limiting, you
must also order heater
diagnostics.
Heater Bakeout:
Heater bakeout is
available on single
phase, and 3 phase/3-leg
models with heater
diagnostics.
