Section C: Using the Face Panel Quick Keys
C – 1: The Set Points Key
The Set Points Key on the front face panel, when
pressed, allows you to quickly change desired feed set
points for the various control outputs that are
enabled.
To change the existing feed set point, first select the
desired option, input the new value, and then press
enter.
Pressing the Set Points key a second time will display
the alarm set points for all of the enabled inputs.
To change the existing alarm set point, first select the
desired option, input the new value, and then press
enter.
C – 2: The Relay Mode Key
Pressing the Relay Mode key on the front face panel
shows you which options have been assigned relays,
and each of the relays' current mode
(AUTO/MANUAL OFF/MANUAL ON) and its
state (Off or On).
Pressing the Relay Mode key again will cycle through
the Relay Modules connected to the controller,
showing what is assigned to those relays and their
current state.
By selecting one of the assigned relays, you are
allowed to choose between automatic, manual on or
manual off. Unused relays and the alarm relay
cannot be manually overridden, but their current
state is always displayed.
If Manual On is selected, you will be prompted to
enter how long the relay can stay in Manual On
before returning to Auto (the maximum on time is
30 minutes).
To test a relay or to prime a pump (on the
local relay screen), lock the screen while in the
main Relay Mode menu, then press the relay's
numeric key (i.e., for relay 3, press the 3 key).
This will turn the relay on for as long as you
are pressing that key. If the relay is already
on, this will have no affect.
The Relay Expansion modules have a button
to test the relays.
If you have the controller set up to control a VFD,
pressing the Relay Mode Key again will display the 4-
20mA Control Outputs.
From here you can switch between auto and manual
on. There are two different manual on options:
Manual % Out and Manual Flow Rate.
Manual % Out sets the VFD output at a specified
value.
Manual Flow Rate changes the VFD output to
maintain a specified flow rate.
