9.10.5 Health Status Digital Output Setting (Optional assignment of Digital Output 1
of Module 0)
Digital Output 1 of Module 0 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. 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.
9.10.6 Disassembly of the P33 Module
No additional disassembly is required, aside from removing the module from the chassis,
to access the relay jumpers.
9.10.7 Digital Output Board (803) Jumper Settings
There are several jumpers for setting the normal state of the output relay contacts. The
board and jumper locations are shown in Figure 19.
