2. JohnsonDiversey Scope of presentation The POF cell knows when most chemicals are being pumped since, except fir a few chemicals such as hydrogen peroxide, most have a conductivity of some 40,000 microsiemens while water has only a conductivity of about 400. POF is switched off in the software for peroxide, mildewcide and any other non conductive chemicals, but the system still can autoprime and autocal given the water use measurement. When attempting to autoprime, if no chemical is sensed within 30 seconds, a �POF Failed� error message is displayed.The POF cell knows when most chemicals are being pumped since, except fir a few chemicals such as hydrogen peroxide, most have a conductivity of some 40,000 microsiemens while water has only a conductivity of about 400.

15. JohnsonDiversey DF2 signals Limited Feature System (LFS) It is possible to configure and install one or more washer networks of the DF2 with limited data logging features by not utilizing trigger module #1, the machine control module. In the LFS configuration, no cycle records will be available. Limited Feature System (one TR7 i/o 2): In the LFS configuration, the Drain and Machine On signals may be connected to the AC inputs of the washer interface module to provide the feed lockout feature of not feeding chemical to an open drain or a washer that is turned off. See AC Trigger above. If the Drain and Machine On signals are not desired, their feed lockout functions can be eliminated by programming the washer setup for reverse logic Machine On signal. The LFS will continue to provide all other DF2 features. Machine On Connect the Machine On signal to the door latch or other appropriate signal. To ensure proper cycle identification, the Machine On signal must be wired to remain uninterrupted for the entire machine cycle. DF2 will not pump chemicals if there is not a valid Machine On signal. Drain Some washers are equipped with two drain systems�reclaim drain and sewer drain. Input channel 2 is used for sewer or main drain, and optionally signal channel 6 is used for reuse drain if necessary. A chemical feed request will be ignored if the drain is open. Cold Water Connect the cold water fill signal to channel 3. Because the cold water signal may be used to monitor the actual time that the water valve is open, the connection should be made to a point in the washer circuit that accurately reflects the status of the valve.

JohnsonDiversey DF2 WIM wiring Washer Interface Modules (WIM) Install one WIM in each washer WIM is a Betalink connection Run 24 VAC + &-, Data + & -, and GND to pump box You can connect all WIM direct to pumpbox, or link one to the next (daisy chain); it works either way since each WIM has a number or address so the pumpbox knows which is which) Connect BetaLink cable shield�s to one another if daisy chaining them together, with the end in the pumpbox connecting to shield/screen connection 4. Note: Never attach the cable shield at both ends. Betalink cable shield protects it from electrical noise, and is connected to GND on the DF2 terminals, and GND on the WIM BetaLink connection is used for longer distance wiring runs as opposed to Alphabus, which is only used for short runs. Betalink cable is powered by the Protocol converter. For DF2 we use the Betalink cable between our WIM and DF2. DF2 uses alphabus for TR7000 and FS1600 wiring. DF1 can use either.Betalink cable shield protects it from electrical noise, and is connected to GND on the DF2 terminals, and GND on the WIM BetaLink connection is used for longer distance wiring runs as opposed to Alphabus, which is only used for short runs.

32. DiverFlowTroubleshooting

33. JohnsonDiversey General troubleshooting principals Never be without a key to allow system access. First step should be to use system events to find errors, next to use interrogation mode to check self diagnostic screens. Use �known good component�, �suspect component� swap method. Most problems are not circuit board related, but are related to air leaks, programming, wiring, and COM port settings Keep good spares available for diagnostics and replacement.

34. JohnsonDiversey Finding air leaks Air leaks can be the source of transport pump errors on the report Low transport pump flow rates can be caused by air leaks Check manifold for bubble leaks from fitting connections If there are no air leaks replace transport pump Most problems are caused by air leaks, which usually result in compromised transport pump flow rates or transport pump errors. This is usually caused by air entering : Somewhere in the manifold (new DF2 oring connection manifolds don�t have this problem) In the chemical pick up line Through a crack in the POF cell A leaky transport pump housing Via an unused chemical Most problems are caused by air leaks, which usually result in compromised transport pump flow rates or transport pump errors.

42. JohnsonDiversey Electrical troubleshooting Voltage felt when making personal physical contact with pump box or any auxiliary and/or Smart Pump Module. Check primary power is properly grounded. Check that hot and neutral are correct and that the primary VAC is correct. Check ground connection from primary supply to transformer to secondary to pump box. Check also for any frayed wiring or loose wire nuts inside transformer Check for correct 24VAC at pump box. Check for tight, no frays, connection on terminal strip. Check for grounding between main module and auxiliary/Smart pump modules. Mounting rail may not be sufficient. Check for moisture on cabinet, behind cabinet (cold wall condensation). Condensation inside main module from hot water evaporation from break tank. Alarm not functioning Verify voltage on wires to alarm; it should be 24VAC if it�s the internal alarm output from DF.

43. JohnsonDiversey Communication Problems First check interrogation mode for correct status, Check smart pumps, Washer Interface Modules (WIM), TR7000, FS1600 selectors for correct addresses. Note that DF1 and DF2 addresses are not all set in the same manner; setting them the wrong way is a frequent mistake. Check both Betalink and alphabus Rx,Tx lights on all modules; if the lights aren�t on a wiring problem is likely. Check all Beta and alpha lines for continuity and that every connection is correct and tight. Check for heat near any cable and proximity to florescent lights, welding or other source of dirty power, EMI/RFI. Check for stable 5VDC on alphabus. Check for miswiring Rx to Tx (TR7 to WIM) Verify system is grounded If the communication cables are draped over motors or other electrical devices, reroute them to eliminate electrical noise, and check that the shielding of the Betalink cables is properly connected in the pumpbox but not on the other end, to minimize electrical noise Swap (changing addresses) with known good module.

If no air leaks are found, it could be the pump is nearing the end of its life and needs to be replaced. If pumps are failing too soon: Ensure continuous water supply Verify no air leaks Verify water temperature in specifications, check for debris in the valves (valve kit available) and add a 20 mesh filter prior to transport pumps. When to change? Change out the transport pump when it�s weeping or the flowrate falls by about 40%, to 1.8 GPM (from 3 GPM) or 0.9 GPM on older 1.5 GPM transport pumps. An extreme test for air leaks one rep used was to disconnect from the transport pumps, paint the manifold with hand dishsoap, and inject compressurized air to look for bubble leaks. Though labor intensive and drastic, heis sites were universally well-maintained and his customers loyal.An extreme test for air leaks one rep used was to disconnect from the transport pumps, paint the manifold with hand dishsoap, and inject compressurized air to look for bubble leaks.
