o
ALARM
– Alarm operation allows for a single set point (Relay ON and OFF at the
same level). Choose between HIGH and LOW operation. Both operations will
require a single set point and a setting for the Hysteresis (HYSTER)
HIGH
– used to control a High Level alarm. Relay will energize (ON) when
the level is above the setting and will de-energize (OFF) when the level falls
below the setting plus the added distance from the hysteresis (HYSTER).
LOW
– used to control a Low Level alarm. Relay will energize (ON) when
the level is below the setting and will de-energize (OFF) when the level rises
above the setting plus the added distance from the hysteresis (HYSTER).
HYSTER
– Used to reduce chatter by creating a hysteresis or differential for
the Alarm set point. The HYSTER value will adjust the OFF position of the
Alarm setting by the HYSTER value.
•
SAFE
– Each relay can be individually configured to its independent fail-safe setting.
Choose between ON, OFF or HOLD
o
ON
– Energizes the relay when a fail-safe condition occurs
o
OFF
– De-energizes the relay when a fail-safe condition occurs
o
HOLD
– Keeps the relay in its current state when a fail-safe condition occurs
•
M-PLEX
– when two or three relays are configured as pumps, they can be inter–connected
to alternate between each cycle. M-PLEX is only available when 2 or more relays are set for
pumps. M-PLEX will not appear when only 1 relay is set for a pump or when the relay
functions do not match (ex: Relay 1 set for a filling pump and Relay 2 set for an emptying
pump). Selecting NO-ALT will turn OFF the M-PLEX.
•
HELP
– Provides setup information, the ability to reset the EchoSwitch II and a simulation
mode to test the relay function
o
SETUP
– Will display the setting for all functions of EchoSwitch II
o
RESET
– Will reset the EchoSwitch II back to its original factory setting
o
SIM-T
– SIM(ulation)-T(est) will allow the end user to simulate changes to level to
verify the relay settings. Using the UP and DOWN buttons will increase
o
TEST P
– This is a production test feature used by the factory to confirm operation.
This mode should only be used when supervised by a Flowline representative.
•
RUN
– Returns the unit to normal measurement and control mode
