Chemical Injection Using Internal 24VAC Control

Transformer

NOTE: Using the Internal 24VAC 300 Milliamp Control

Transformer is recommended by Alliance Laundry Sys-

tems.

IMPORTANT: DO NOT remove the red jumper wire from

the terminal strip.

There are 3 terminals necessary for this connection option.

• Terminal “24VAC COM” is used to connect one side of the

internal control transformer to the external dispenser input

signals common.

• The second terminal is used to connect the other side of the

control transformer to the machine output signals common

through a red jumper wire between “24VAC” and “RELAY

COM”. Refer to Figure 27 .

IMPORTANT: Do not use the transformer terminals if

an external power supply is used.

Chemical Injection Using External AC Power Source

NOTE: An External AC Power Source is NOT provided

by Alliance Laundry Systems.

NOTE: Power for external supplies must not be derived

from the high-voltage main power connection point.

IMPORTANT: The external power must supply power of

240VAC or less and be protected at 3 Amps or less.

1. Remove the red jumper wire installed by the factory between

“24VAC”, and “RELAY COM”.

2. Connect one side of the external power to the “RELAY

COM” and the other to the external dispenser input signals

common. Refer to Figure 28 .
