External Supplies
For proper communication between the machine and an external
chemical supply system, it is important for the low-voltage signal
power to be connected properly. The included wiring diagram
shows several different options for safe and correct wiring of this
interface.
The preferred method for connecting the wiring from the external
chemical supply system to the machine is to use the 300mA pow-
er of the machine’s 24VAC control transformer, which is intended
strictly for this purpose. Refer to
and
. Other
voltage and current options are available, but require some wiring
changes and must be provided with an external power source.
Under no circumstances should the high-voltage machine supply
connections or source be used for the communication wiring.
Communication wiring connections, which is H2 a single row
green connector on a small output board, can be found under a
service panel at the upper back of the machine.
Chemical Injection Using Internal 24VAC Control
Transformer
NOTE: Using the Internal 24VAC 300 Milliamp Control
Transformer is recommended by Alliance Laundry Sys-
tems.
CAUTION
Do not attempt to increase fuse rating or alter wiring
of external chemical supply terminal strip in such as
way that may conflict with the suggested methods
provided on the Optional External Supply Wiring Dia-
gram.
