A12. MULTI-FUNCTION OPEN COLLECTOR OUTPUTS
Two Open Collector Outputs are provided, which can be programmed for Run, Fault, Target
Frequency, Frequency Threshold Level (> 8.04 – 8.05), Frequency Threshold Level (< 8.04 + 8.05), I2t
or I•t Fault, Load Loss, External Fault, and Motor Overload. Open Collector Output 1 is factory pro-
grammed to operate as a Target Frequency indicator (Function No. 8.02 set to “0002” (factory set-
ting)). Open Collector Output 2 is factory programmed to operate as a Frequency Threshold Level
(< 8.04 + 8.05) indicator (Function No. 8.03 set to “0004” (factory setting)). See Figure 39, on page 54.
See Table 17, on page 54, for the Multi-Function Open Collector Output electrical Ratings.
Multi-Function Open Collector Output 1
Collector (O.C.): TB1 Terminal “11”.
Emitter (COM): TB1 Terminal “12” (internal circuit common).
Multi-Function Open Collector Output 2
Collector (O.C.): TB1 Terminal “13”.
Emitter (COM): TB1 Terminal “14” (internal circuit common).
Multi-Function Output Relay 2 Contacts
Normally Open (N.O.) Contact: TB1 Terminal “26”.
Common (COM): TB1 Terminal “27” (contact common for Relay 2 only).
Normally Closed (N.C.) Contact: TB1 Terminal “28”.
