Chiller timer
When the time required by the chiller to reach working temperature hinders productivity,
you can turn the chiller on before the start of the shift. Use the chiller timer to turn the
chiller on before the press is turned on.
If the press enters the Ready state after being turned on, bypass the chiller timer. Chiller
bypass is the default timer state.
You can set the chiller timer to three On/Off functions per day. Setting the timer On turns
on the chiller independently of the press status. The press command of the chiller
overrides the chiller timer command.
Set the timer to On about 30 minutes before the start of a shift. Set the timer to Off 30
minutes after the start of a shift. This ensures that the chiller is turned off only at the end
of the workday.
The chiller timer is located behind the electronics cabinet, below the Main Power switch.
