3.OO operation
3.O3 Product LEDs
There is one LED for each product button; Detergent, Rinse and Sanitizer (if present). The LED is used to convey pump
status, maintenance alarms or critical alarms. Critical and maintenance alarms details are in Section 5.05 “Configure Alarms”.
3.O1 Dispenser Control Pad
There are three or four buttons and corresponding LEDs on
the DMx depending on whether a 2-product or 3-product
system is in use. These buttons and LEDs allow for local
interaction by the user.
LED Color Fixed or Flashing Buzzer Indication
Green Flashing
Off Pump is operating normally as part of a rack or is priming with no maintenance alarms or critical alarms.
Fixed
Off There is an active detergent or rinse signal present and the pump is not dosing.
Red Fixed
On
This indicates that there is an out of product condition that the local staff can manage. This can be triggered for
detergent if the dispenser is being run in probe mode and there are a configured number of racks run below the
setpoint.
Alternatively, this can be triggered on Detergent, Rinse or Sanitizer by using a depletion wand accessory
Flashing
On
This indicates that there is a critical alarm on one of the pumps that requires intervention by a technician.
Depending on the product LED that is flashing, the following conditions are causes:
• Detergent probe faulty (probe mode only)
• Rinse temperature is low (requires optional rinse temperature sensor kit)
• Detergent, Rinse, or Sanitizer pump jam
Orange Fixed
Off
This indicates that there is a non-critical maintenance alarm that the local staff can manage. The conditions that
produce this type of alarm are:
• If the detergent LED is illuminated, the Detergent tank temperature is low (requires optional temperature
compensated probe)
• All 3 LEDs are illuminated the Change Tank Water Alarm has been triggered based on the number of racks
run since the last change.
Flashing
Off
This indicates that there is a non-critical maintenance alarm that requires intervention by a technician. The
conditions that produce this type of alarm are:
• If all product LEDs are flashing once per second, the dish machine needs to be delimed based on the
number of days since the last delime.
• If Detergent, Rinse, or Sanitizer are flashing twice per second, the corresponding pump is due to have a
squeeze tube change according to the number of days of operation since the last change.
DETERGENT RINSE AID SANITIZER POWER
3.O2 Product Buttons
There is one button each for Detergent, Rinse, and Sanitizer. (Sanitizer used only on a 3-product system.) These buttons are
intended to be used for the following purposes:
Priming
Only one pump can be primed at a time. To begin priming press any product button while the dispenser is idle. Attempts to
prime while a detergent or rinse signal is active will be ignored. While the pump is priming, the green LED will flash once poer
second. Prime limits are configurable using the Hydro Connect Mobile Application within Bluetooth range, but the default
prime limit is 30 seconds every hour. If the button is pushed a second time before the limit has expired, the priming operation
will stop, and the LED will turn off. The priming operation can be repeated multiple times until the limit is reached. After the
limit is reached, further attempts to prime will result in the product LED flashing orange once, indicating that the user must
wait until the configurable lock-out period has elapsed.
Silencing the Buzzer
Critical alarms on the DMx will result in the sounding of an audible buzzer along with a solid or flashing red LED. Solid red
indicates that the local kitchen staff can address the issue and flashing red indicates that a technician is needed. The buzzer
can be muted for 10-minutes by pressing any button on the dispenser for a duration of one second. If the alarm is not cleared
in 10-minutes, the buzzer will sound again.
Clearing Alarms
Most alarms can be cleared by pressing and holding the button on the affected product for a duration of 2 seconds.
Alternatively, these alarms can be cleared with instruction from the “Manage Dispenser” screen in the Hydro Connect Mobile
Application. The "Manage Dispenser" screens are described in more detail in Section 4.06 on page 23.
