The iQpump Micro is operated in HAND mode by performing the following tasks:
·
Program all parameters
· Verify motor rotation direction
19. HAND MODE
Press to access HAND Speed. Use to change HAND Speed value.
Press to save value.
Set parameter P5-01 ‘HAND Mode Ref.’ to ‘0’ to adjust the hand mode reference
from an external 0 – 10V signal connected to terminals TB1-1, A1 and AC.
Hand Speed Reference from Analog Input (0 to 10 Vdc)
PRESS TO TURN OFF
PRESS HAND MODE

Sleep and Anti-No-Flow (ANF) Detection
NOTE: Ensure the pump system is regulating pressure/flow satisfactory while operating under normal running conditions prior to
adjusting Anti-No-Flow operation.
Verify No-flow/Sleep operation
a. Continue to Step 1 below if pump operation is sstable.
b. Disable Anti-No-Flow function if pump operation is u
unstable.
-Set parameter P2-23 = 0.00% and adjust PI control parameters b5-02 and b5-03 to stabilize pump system.
-Refer to the iQpump Micro User Manual (Document No.TOEPYAIQPM03) for additional information.
c. Re-enable the Anti-No-Flow function by setting P2-23 to 0.40% and continue to Step 1 to verify no-flow/sleep operation once the
system is stable.
Step 1: Verify the system holds pressure by creating a no-flow situation (e.g. close off discharge valve).
Step 2: Press the OFF button on the digital operator, wait 1 minute until system stabilizes and verify system pressure feedback
using parameter U1-91. Adjust P2-25 to the actual delta pressure drop plus 1 PSI if the pressure drops more than 3 PSI (use
Monitor U1-91).
Example: Setpoint is 80 PSI, pressure feedback U1-91 shows 76 PSI, P2-25 should be 4 + 1 or 5 PSI.
Note: This value should always be more than the P1-04 Start Level. If not, the system pressure is not holding and must be
corrected or the pump system will continue to cycle on and off.
Step 3: Operate the system in normal AUTO operation with flow. Observe monitor U1-99 “ANF Timer” and verify the value is
increments and resets to zero continuously. If the value holds at 10 sec. (P2-24) increase P2-24 “Anti-No-Flow Detection Time” by
increments of 5 seconds. Repeat Step 3 each time P2-24 is adjusted.
Step 4: Create a no-flow situation (e.g. close discharge valve). Use monitor U1-99 “ANF Timer” to verify the value is increments
and holds at the P2-24 time (value set in Step 3). Once the Anti-No-Flow timer expires, the speed will reduce gradually until
reaching minimum pump speed (P1-06) where it will hold for 5 seconds according to P2-03, before going to sleep.
Step 5: Operate the system in normal AUTO operation and verify sleep and wake-up functions satisfactory.
