EZ Installation
Instructions
(cont'd.)
4.
If a Secondary VendingMiser is being installed, use the supplied 3 Meter (10 feet) phone style cable to connect the
OCCUPANCY SENSOR connector on this VendingMiser to the REPEATER connector on the Primary Vending-
Miser. Only remove the yellow label coving the REPEATER connector on the previous unit in the chain. Addi-
tional Secondary VendingMisers can be daisy-chained using the same techniques shown in the diagram to the right. A
maximum of four Misers can be daisy-chained in this fashion. It is acceptable to mix VendingMisers with SnackMisers,
PlugMisers, and/or CoolerMisers provided the sensor coverage is acceptable for all devices sharing the sensor.
Validate The Installation
5.
Plug the vending machine's power cord into the VendingMiser. Then, plug each VendingMiser's power cord into
the wall outlet. The following should occur:
• The vending machine should power up immediately.
• The Green LED should flash twice to indicate that the temperature sensor is functional.
• The Amber LED should then come on as the VendingMiser attempts to synchronize with the compressor's
operation. This typically will require that the compressor cycle on and off.
• The Red LED should come on, indicating occupancy detection.
The PIR sensor must be allowed to stabilize for several minutes before its placement can be verified. Once the
sensor is warmed up, it will flash at the slightest movement within its field of view. Validate that the sensor can
"See" an occupant at, or approaching, all machines controlled by this sensor. If necessary, relocate the Primary unit and
repeat the coverage test. The Red LED on the VendingMiser will mirror the state of the PIR sensor, with an additional
3 second delay. This verifies that VendingMiser is communicating with the PIR sensor.
6.
As a final functional test, the VendingMiser will power-down the
first time only after installation approximately two minute after the
area around the machine is vacant and the compressor is determined
to not be running. Covering the occupancy sensor will allow valida-
tion of the power-down operation if so desired. Following this ini-
tial power-down, the VendingMiser will operate with its standard 15
minute time-out.
NOTE:
The VendingMiser will flash all three LEDs simultaneously and
light a RED LED in the Occupancy sensor if the vending machine has
failed and will not shut down its compressor after several hours of use.
Since this prohibits the VendingMiser from shutting down the machine,
please call the machine owner service line for machine service.
