tESt Test Menu
tESt When selected the unit simulates a pressure input over the range to test the programming and output
function. To start an automatic simulated cycling through the pressure range press the E key. This test
will run continually until the E key is pressed again. To manually adjust the simulated pressure
press the ▲ or ▼ key to adjust the pressure value. To exit tESt press the MENU key.
FAIL Failsafe Menu
The Failsafe menu is used to set the relay and transmitter outputs to certain preset values when failsafe conditions
occur. Error codes will show on the display indicating the problem. See Diagnostic Error Messages on the next page.
rEL Relay Output Failsafe Condition
OPEN
The relay is de-energized upon failsafe condition. The NO contacts will be
opened, and the NC contacts will be closed.
CLSE The relay is energized upon failsafe condition. The NO contacts will be closed,
and the NC contacts will be opened.
NORM No change applied to the relay upon failsafe condition.
OUtP sets the transmitter output option failsafe condition for a unit with the output option of 4 to 20 mA, 0-5 VDC,
0-10 VDC, 1-5 VDC, or 1-6 VDC. See below chart of transmitter output action according to output signal type.
OUtP Transmitter Output Failsafe Condition
LOW
Transmitter output goes to low failsafe condition.
HIGH Transmitter output goes to high failsafe condition.
NORM No change applied to transmitter output upon failsafe condition.
FrEs Failsafe reset
AUTO
Automatic reset - Failsafe is reset automatically when the failsafe error condition
is removed.
HOLD Manual reset - Failsafe is reset when the MENU key is pressed.
