Health Status Digital Output Setting (Optional assignment of Digital Output 1)
Digital Output 1 may be assigned to operate when the value of the Health variable is <1. To
set up Digital Output 1 in this manner, it is necessary that the Relay Output 1 Connection
Jumper be set for Normally Closed operation (see Setting Digital I/O jumpers section which
is included in this Appendix A3). Therefore, during normal operation, the unit is actively
holding the contacts of the output relay open (no alarm). If an erroneous operation is
detected, or there is a power supply failure, the contacts of the output relay will close (alarm).
The function of this output may be assigned for Health status by using the 70 Series
Configurator along with the Normally Closed jumper connection installed for Relay output 1.
