Drain Mode - Idex Knight On-Premise Pro Instruction Manual

DRAIN MODE

Drain mode counts the number of times the drain
solenoid is energized during the machine's operating
cycle, and chemicals are injected by their programmed
(assigned) drain number.
Activation of the ―load count pump‖ ends the current
formula and prepares the OP-Pro to run the next
washcycle. Pump 7 is the default load count pump when
using drain mode. For each formula, pump 7 should be
assigned to the final drain number. This ensures the
formula is properly ended, even on machines where the
drain signal occurs again after the last chemical
injection.

Connect the machine's drain signal to pump 1 input
on the signal interface module (SIB).

Program chemical formulas according to the
instructions on pages 8 – 9. Pumps can have a
second injection ―level‖ if required, however the
second level must be assigned to a later drain
number than the first.

Program the flush time (if manifold is used).

During operation, the upper display will show the
current drain count. This is signified by the letter ―d‖
as the first character of the display.
Enabling or disabling drain mode:
(1) Enter the access code if you do not already have
access to the system.
(2) Select pump 5, and formula A.
(3) Use  to choose 000 (disable) or 001 (enable) on
the 3-digit display, then ENTER.
DISABLE
000
ENABLE
(4) The display will flash briefly, indicating that the
enable/disable status was accepted.

Assigning drain numbers:
(1) Enter the access code if you do not already have
access to the system.
(2) Press MODE until both the pump time and delay
time LEDs are flashing.
(3) Select the formula and pump.
(4) Use / to input the drain number, or to change an
existing drain number (max is 15). Multiple pumps
can run on any drain occurrence, however you may
wish to use delay times to ―stagger‖ the pumps
operation.
(5) Press ENTER and the display will flash briefly,
indicating that the drain number was accepted.
(6) Repeat steps 3 – 6 for all formulas and pumps that
will be used.
Inverting drain mode signal:
The washer's drain mechanism will typically energize
the solenoid to close the drain and de-energize to open
the drain. This type of drain activation is standard on
almost every Wascomat, Milnor and Uni-Mac washer,
however Drain Mode can be set to recognize an
―inverted‖ signal (one that energizes to open the drain) if
necessary.
(1) Enter the access code if you do not already have
access to the system.
(2) Select pump 6, and formula A.
(3) Use  to choose 000 (normal) or 001 (inverted) on
the 3-digit display, then ENTER.
001
(4) The display will flash briefly, indicating that the
normal/inverted status was accepted.
