Annunciation Contacts
Contacts for customer use are provided and wired to TB1 and TB2 as follows for use as annunciators of Bypass unit
operation. All are 5 amp at 120 VAC contacts.
Programmable Output Relays 1, 2 and 3 may be re-programmed via DIP switches S2 and S3 on the Bypass Control
PCB A2. These relays provide form C “dry contacts” for customer use in annunciation to Building Automation Sys-
tems or general duty in other control logic circuits. Each contact is rated for 5 amps at 120 VAC.
The additional programmable output relay functions are described in the table below:
See Table 1.3 for DIP switch positions required to achieve these functions.
