WATLOW Series 922 User's Manual

"Read Me First."

Congratulations, you're about to become a fully-qualified user of the Watlow

Series 922! This versatile microprocessor-based ramping control is powerful,

yet simple to learn. A ramp progresses from one set point to another set point

over a period of time. In this chapter of the user's manual, you'll get an

overview of the 922 and its operation.

Figure 1 is a simplified view of the Series 922's capabilities. It is a 2-channel,

dual output per channel, microprocessor-based, 1/4 DIN-sized ramping

temperature control. The 922 accepts dual inputs, one per channel. This

includes Type J, K or T thermocouple, a 1° or 0.1° RTD input, or one of two

process inputs. You can order an external event output board with two or eight

auxiliary outputs. It has a full control temperature range, offset calibration, and

a front panel lockout feature.
