INSTALLATION

 

 

 

 

The sequencer may be mounted in any position and location provided that the temperature does not exceed the U.L. ambient rating.

Follow the original equipment manufacturers' recom- mendations for the proper location.

Wiring

All wiring must conform to local and national electrical codes and ordinances.

The terminal markings are equivalent to most other manufacturers' types. Follow the original equipment manufac- turers' recommendations for proper wiring.

DEFINITIONS

MAIN CONTACTS: These are the load contacts and are identified by the terminals designated “M”. The M1-M2 contacts will always be the first set of contacts to close and the last set to open. The M3-M4 contacts will always be the second set of contacts to close and the second-to- last set of contacts to open. The M5-M6 contacts will always close last and open first.

AUXILIARY CONTACTS: These contacts are identified by terminals designated “A”. During the ON cycle, these contacts complete the control circuit to subsequent se-

quencers when more than one is required. These con- tacts will close after all main contacts have closed and will open before any of the main contacts open.

FAN INTERLOCK: When multiple sequencers are used, U.L. requires a fan interlock circuit which will guarantee that the fan will stay on until all heating elements are de- energized. The fan interlock circuit must be the first set of contacts to close and will normally be marked “M1-M2”.
