General User Information______________

Cold Start (Initial/First Use)

Appliance is programmed at the factory as follows:

Dryer 6 min. dry time/quarter (coin 1) $.25 dry price

Warm Start (After Power Failure)

A few seconds after power is restored, if a cycle was in progress at the time of the power failure, the display will prompt “Select Cycle to Restart”. This is to indicate the need for a fabric setting keypad to be pressed to restart dryer.

Pricing

After the door is opened following the completion of a cycle, the display indicates the cycle price (unless set for free operation). As coins or debit inputs arrive, the display will change to lead the user through the initiation of a cycle.

There are 3 types of pricing:

Fixed Cycle

A dryer set up for “Fixed Cycle” operation can only accept additional time accumulated by increments equal to the cycle price.

Top Off

A dryer set to offer “Top Off” capability will allow time to be added to an existing dry cycle in increments equal to the number of minutes of dry time per quarter (coin 1), up to 99 minutes, regardless of the cost required to start the machine. When the cycle price is not the same as the denomination of coin 1, credit in escrow will be applied at a maximum of the cycle price per key press. When the cycle price is equal to coin 1, all credit in escrow will be applied with a single key press (Accumulator Mode).

Note

A maximum of 99 minutes may be purchased; no

!

additional credit is given when 99 minutes is in the

display.

Important

Read all instructions before operating.

!

The fabric setting key pads along with the digital display are used to setup the dryer controls.

How to use the Keypads to Program the Controls

The WHITES & COLORS keypad is used to increment numbers and scan through menu locations.

The PERMANENT PRESS keypad will enter program locations and save changes made.

The DELICATES keypad is used to decrement numbers and scan through menu locations.

To back out of a program location hold the DELICATES button and then press the PERM PRESS button.

Start Operating Setup

Caution

The service access panel must not be opened

!

unless power is first disconnected from the dryer.

Before proceeding it is worth noting that, despite all the options available, an owner can simply choose to uncrate a new commercial machine, hook it up, plug it in and have a unit which operates.

Note

On stacked dryers programming selections apply

!

to both dryers.

Entering and Exiting Service Mode

Entering

Transition the service switch to enter the service mode. Service mode can also be accessed via ADC data acquisition (DA) communications. Please note that only the “vending parameters, count settings, and clock settings” will be available with this method.

Exiting

First make sure the perm press key has been depressed to save any changes that have been made and then transition the service switch.

Free Cycles

This is established by setting the cycle price to zero. When this happens “SELECT CYCLE” will appear rather than a cycle price. When the cycle price is set to zero, only one cycle time is allowed to run. Multiple key presses will not add time and a free cycle will automatically terminate when the door is opened.

Faults___________________________________

(D17 Upper) (D6 Lower) Exhaust Probe

An exhaust probe fault occurs when the control detects that the exhaust temperature transducer is reading a temperature that is out of the probe’s normal operating temperature range for more than 3 seconds. If the probe fault occurs in a drying cycle the control will enter the fault cool down mode and will run for the full 3 minutes of fault cool down; the control will not be able to shut down based on temperature. Fault cool down can be exited if the fault is manually cleared by entering the diagnostic cycle for more than 3 seconds. There is an automatic fault clearing feature for this fault. If the fault condition no longer exists, the control will clear the fault condition and return to READY mode.

(D18 Upper) (D2 Lower) Axial Probe

An axial thermistor probe fault occurs when the control detects that the axial thermistor is reading a temperature that is out of the probe’s normal operating temperature range for more than 3 seconds, usually an open or shorted probe condition. If the probe fault occurs in a drying cycle the control will enter the fault cool down mode and will run for the full 3 minutes of fault cool down, the control will not be able to shut down based on temperature. Fault cool down can be exited if the fault is manually cleared by entering the diagnostic cycle. There is an automatic fault clearing feature for this fault. If the fault condition no longer exists, the control will clear the fault condition and return to READY mode.

(D21 Upper) (D7 Lower) Sail Switch Closed

A sail switch closed fault occurs when a cycle is starting up from either READY mode, PAUSE mode or any other idle state. Once a temperature/cycle is selected the control will start the time and verify the sail switch is open, if it is not, the control will display on the screen that the control is “STARTING” and will not turn on the FAN, DRIVE or HEAT. The control will allow the sail switch 30 seconds to open before the control faults out with a SAIL SWITCH CLOSED FAULT. Once a SAIL SWITCH CLOSED FAULT is detected the control will log the fault and will not allow the cycle to continue. The control will display “SAIL SWITCH CLOSED FAULT, SELECT TEMP TO RESTART, when the fault is detected.

(D20 Upper) (D4 Lower) Sail Switch Open

A sail switch open fault occurs when a cycle is starting from either READY mode, PAUSE mode or any other idle state. If the sail switch does not close within the allotted 10 seconds the control will log the fault and will not allow the cycle to continue. The control will display “SAIL SWITCH OPEN FAULT, CHECK MAIN DOOR AND LINT ACCESS AND SELECT TEMP TO RESTART.” A sail switch open fault can also occur once a cycle is in process. If the control detects that the sail switch has opened, the heat will immediately turn off and if the sail switch fails to close within the allotted 30 seconds, the control will fault and display “SAIL SWITCH OPEN FAULT, CHECK MAIN DOOR AND LINT ACCESS AND SELECT TEMP TO RESTART.”

113420-1 www.amdry.com 9

(D22 Upper) (D8 Lower) Latched Heat Relay

A latched heat relay fault occurs when the control detects that the heat relay contacts are closed when the heat output should be off. In the event the control detects that the relay is closed and the heat signal should be off, the control will immediately shut down and will open the interposing relay.

(D23 Upper) (D15 Lower) Burner Return Voltage

A burner return voltage fault occurs when the control detects that the burner return signal is active but the heat relay contacts are open and the heat output should be off. This fault only pertains to a gas dryer model. In the event the control detects that the signal is active and the heat signal should be off, the control will immediately shut down and will open the interposing relay.

(D14 Upper) (D12 Lower) Rotation Sensor Fault

A rotation sensor fault occurs when the control is in a cycle and does not detect any rotation sensor pulses in more than 10 seconds. At which point the control will enter fault cool down mode where the fan will remain active for 3 minutes or the exhaust probe temp is below 100° F.

(D19 Upper) (D3 Lower) Exhaust High Temp Fault

An exhaust high temperature fault occurs when the exhaust probe is detecting a tumbler temperature that is 20° F above the max dryer temperature set point for more than 10 seconds. At which point the control will enter fault cool down mode until the exhaust temperature probe reads less than 100 ° F or the dryer has been in fault cool down for more than 3 minutes.

Events__________________________________

(E1 Upper) (E4 Lower) Radiant Sensor Fault Count

A radiant sensor fault count will occur when a gas model dryer attempts to turn on the burner system and never receives a 120V return signal on the gas return signal within a predefined time. This is considered an event and a counter will keep track of how many times this fault condition is occurring.

(E2 Upper) (E5 Lower) Burner Ignition Fault Count

A burner ignition fault count will occur when a gas model dryer attempts to turn on the burner system and receives a 120V on the burner return signal but it does not transition to a 0V return signal within a predefined time.

(E3 Upper) (E6 Lower) Exhaust High Limit

This location is a count of the times that the exhaust high limit has been sensed in the open position.

(E7 Coin 1) (E8 Coin 2) Bad Coin Count

This location is a count of all the bad coin occurrences that were detected from the coin input.

(D5 Coin 1) (D13 Coin 2) Blocked Coin Drop

This diagnostic code occurs if the control senses a blockage in the coin input. If the coin input is blocked for more than 8 seconds the control will go to out of order and will not allow the control to start a cycle. This fault has both automatic and manual fault clearing. If the condition is corrected the control will recover from out of order immediately after the blockage is no longer seen.

D16 – Gen 2 Card Reader Did Not Communicate In Previous 5 Minutes

This fault occurs when the control has lost communication with the Debit Card reader. When this fault occurs the control will log the fault and will display D16 on the display instead of the cycle price information.
