MULTI-PARAMETER CONTROLLER & ANALYZER USER’S MANUAL
Section 3 - Electrical Connections and Setup
3.10 MANUAL TEST MODE
(LCD MENU SECTIONS - pH: 4.4, ORP: 5.3, Conductivity: 6.4, Flow: 7.2)
Once the relays are configured, the setup can be
tested using Manual Test Mode to simulate process
changes.
MANUAL TEST MODE is used to simulate a process
reading in order to verify the correct response of the
outputs. When in the MANUAL TEST MODE, the
relays and outputs are no longer placed on hold as
they are when in the rest of the menu. The relays and
outputs will react to the simulated change in process
as if the Shark was in RUN MODE.
Note that when the user exits the MANUAL TEST
MODE, the relays and outputs will remain in the
MANUAL TEST MODE state until the user enters
RUN MODE.
3.11 RELAY OVERRIDE
(LCD MENU SECTION - pH: 4.5, ORP: 5.4, Conductivity: 6.5, Flow: 7.3)
Relay Override is used to manually override the state
of the relays. The user is able to set the operating
mode of the relay as AUTO/ON/OFF (the default and
RUN MODE states are AUTO).
This feature can be used to energize or de-energize
the relays to manually correct the process, or to shut
down an ancillary device to perform maintenance.
When in the RELAY OVERRIDE mode, the relays are
no longer placed on hold as they are when in the
other menus.
Note that if the RELAY AUTO RETURN is set to
"ON", the controller will place all the relay settings
back to AUTO 10 minutes after the Shark returns to
the run mode..
