The 745 has the ability to override the normal function of all outputs, forcing each to
energize and de-energize for testing. Enabling this feature turns the In Service LED
off and the Test Mode LED on. Refer to FIGURE 5–48: Output Relays Scheme Logic
on page 5–89 for the output relay scheme logic.
• FORCE OUTPUT RELAYS FUNCTION: Select Enabled to enable the output
relay testing feature and override normal output relay operation. This setpoint
is defaulted to Disabled at power on.
• FORCE OUTPUT 1 to 8: Select "Energized" to force Output 1(2-8) to the
energized state or "De-energized" to force Output 1(8) to the de-energized
state. This setpoint is only operational when output relay testing is enabled.
• FORCE SELF-TEST RLY: Select Energized to force the self-test relay to the
energized state and De-energized to force to the de-energized state. This
setpoint is only operational while the output relay testing feature is enabled.

FORCE ANALOG OUT 7:
MESSAGE
De-energized
The 745 has the ability to override the normal function of analog transducer
outputs, forcing each to any level of its output range. Enabling this feature turns the
TEST MODE indicator on and de-energize the self-test relay.
• FORCE ANALOG OUTPUT FUNCTION: Select Enabled to enable the analog
output testing and override the analog output normal operation. This setpoint
defaults to Disabled at power on.
• FORCE ANALOG OUT 1 to 7: Enter the percentage of the DC mA output range
of Analog Output 1(7). For example, if the analog output range has been
programmed to 4 to 20 mA, entering 100% outputs 20 mA, 0% outputs 4 mA,
and 50% outputs 12 mA. This setpoint is only operational if analog output
testing is enabled.
