O&M Manual
Rev F (8/17)
Iout#1 Mode This function sets analog output #1 to either track PAA (default) or
enables the PID controller to operate on the PAA input. Press ENTER to
initiate user entry mode, and the entire value will flash. Use the UP
arrow key to modify the desired value; selections include 1-ppm for PAA
tracking or 2-PID for PAA PID control. Press ENTER to store the new
value.
*Iout#2 Mode This function sets analog output #2 for temperature (default), PAA, or
pH. Press ENTER to initiate user entry mode, and the entire value will
flash. Use the UP arrow key to modify the desired value; selections
include 1-C/F for temperature, 2-ppm for PAA, or 3-pH for pH. Press
ENTER to store the new value.
*Iout#3 Mode OPTIONAL. This function sets analog output #3 for temperature (default)
or PAA. Press ENTER to initiate user entry mode, and the entire value
will flash. Use the UP arrow key to modify the desired value; selections
include 1-C/F for temperature or 2-ppm for PPA. Press ENTER to store
the new value.
*Rly A Mode Relay A can be used in three different ways: as a setpoint control, as a
fail alarm, or as a HI-LO alarm band. The three settings for Rly A Mode
are CON, FAIL and AL.
The CON setting enables normal control operation for Relay A, with
settings for setpoint, hysteresis, delay and phasing appearing in the
CONFIG menu automatically. See Figure 25 for further details.
The FAIL setting enables the fail alarm mode for Relay A. Relay A will
then trip on any condition that causes the FAIL icon to be displayed on
the LCD. Using this mode allows the User to send alarm indications to
other remote devices.
The AL setting allows two setpoints to be selected for the same relay,
producing a HI-LO alarm band. In this mode, Relay A will trip inside or
outside of the band, depending upon the Phase selected. See Figure 26
for further details.
Relay B Mode Relay B can be used in a number of ways: as a setpoint control, or as an
Relay C Mode alarm. The two settings for Relay B Mode are CON and FAIL.
The CON setting enables normal setpoint operation for Relay B. Relay B
then operates identically to Relay A, with settings for setpoint, hysteresis,
delay and phasing appearing in the CONFIG menu automatically. See
Figure 25 for details.
*Relay D Mode OPTIONAL. Relays D, E, and F can be used in two ways: as a setpoint
*Relay E Mode control, or as an alarm. The two settings for Relay B Mode are CON and
*Relay F Mode FAIL.
