2 . AQUASWITCH I and AQUASWITCH II
For AQUASWITCH II users, the term “Controller” refers to the
ASII Monitor/controller Circuit Board functions.
1. Turn the Purge Cycle trimmer adjustment screw fully
clockwise to obtain an approximate one minute cycle.
(See figure V.A.1)
2. Adjust Controller “Set Point” to simulate “GOOD” water
quality (for the
AQUASWITCH II , turn the Set Point
trimmer adjustment screw counterclockwise (see
Section IV.B.2 and See figure V.A.1 )) and verify the
following sequence of operation.
3. Push “BANK SWITCH” several times to verify the
following Controller operations.
a.
Verify that the “IN USE” indicator lights switch ON
and OFF between Banks A and B each time “BANK
SWITCH” is pressed.
b. Verify that both Banks A/B “GOOD” water quality
lights remain ON.
c. Verify that the “BLEED” light remains OFF.
d. Leave BANK A ON for next step. (If required, push
the “ALARM RESET” switch to reset alarm.)
NOTE: If the Logic Module Alarm Reset jumper has been
installed to provide the user with the optional Manual Bank Switch
alarm condition, the alarm will be activated each time the “BANK
SWITCH” is pressed. Otherwise, the alarm will be activated only
when the Purge Cycle time setting has expired. (Refer to Section
V.C)
4. Adjust Controller Set Point to simulate “POOR” water
quality. (For the AQUASWITCH II , turn Set Point
trimmer adjustment screw clockwise, and verify the
following sequence of operation.)
a. BANK A water quality indicates “POOR.”
b. Yellow “BLEED” light turns ON and water is purged
from system. (This should continue for about 1
minute.)
c. After 1 minute, BANK A will turn OFF and BANK B
will turn ON and indicate “POOR” water quality.
d. After approximately 1 minute, BANK B should turn
OFF, the “BLEED” light should turn OFF, the Bleed
valve should close and the alarm should be
activated. The system is now entirely shut down.
NOTE: If an external alarm is connected, it will be activated when
the
AQUASWITCH switches Banks. (Press the “ALARM
RESET” switch to turn OFF alarm.)
If an alarm is not connected, an alarm condition can be monitored
by connecting an ohm meter (DVM) across Power Board Alarm
Terminals COM and NO. The meter should indicate a CLOSED
CIRCUIT when in the alarm condition.
5. Adjust the Controller Set Point to simulate “GOOD” water
quality. (For the AQUASWITCH II, turn Set Point trimmer
adjustment screw counterclockwise and verify the
sequence of operation.)
6. Press the “BANK SWITCH.” The BANK A “IN USE” and
“GOOD” water quality indicator lights should turn ON.
Press the “BANK SWITCH” again and BANK B “IN USE”
and “GOOD” water quality indicator lights should turn
ON.
7. Complete the following steps to return the
AQUASWITCH to its normal operating status.
a. Using the “BANK SWITCH,” select the desired Bank “IN
USE” status.
b. Adjust the Controller “Set Point” to the desired minimum
water quality. (Refer to Section IV.B.2 and figure V.A.1. )
c. Set Purge Cycle to the desired time delay. (Refer to
Section V.B)
