Setting Up Pump Staging
To avoid an excessive power demand at your facility when the conveying system starts up,
you can stagger the times at which pumps start. Whenever a demand would cause two pumps
to start simultaneously, your choice for pump staging sets the delay between the start of one
pump and the start of the next. The factory default is a delay of three seconds. You need to
change this setting only if this delay is too long or too short for your facility.
To set the delay between the start of one pump and the next:
1. Go to the System Setup screen if needed.
To reach this screen from the Station Summary or Pump Summary screen, touch and
hold the icon for any station or pump, until the Station n Operator or Pump n Setup
screen appears. Then touch System. The System Setup screen appears.
The current delay is displayed under Pump Staging.
2. Touch Pump Staging.
A keypad pops up, with an entry of 0.
3. Enter the number of seconds (range: 1–99). Use ← to erase any mistakes. Use ↵ to
enter the value.
The keypad disappears and the new setting appears under Pump Staging.
Setting Up Touch Switch Delay
During operation, the controller normally displays the Station Summary screen or the Pump
Summary screen, showing the current status of all stations or pumps. Briefly touching the
icon for a station or pump toggles between taking it offline (disabling it) and putting it online
(enabling it). Touching the icon and holding it takes the user into the controller’s menu
system. The setting for touch switch delay determines how long the user must keep an icon
touched before a menu appears. The factory default is 1.5 seconds. You need to change this
setting only if you find that users are having difficulty with the current setting.
To change the touch switch delay:
1. Go to the System Setup screen if needed.
To reach this screen from the Station Summary or Pump Summary screen, touch and
hold the icon for any station or pump, until the Station n Operator or Pump n Setup
screen appears. Then touch System. The System Setup screen appears.
The current delay is displayed under Touch Switch Delay.
2. Touch Touch Switch Delay.
A keypad pops up, with an entry of 0.
3. Enter the number of seconds (range: 0.0–99.0). As with many ATM machines, the
first digit you enter initially appears to the right of the decimal point and moves to the
left as you enter more digits. You do not need to use the decimal point. Use ← to
erase any mistakes. Use ↵ to enter the value.
The keypad disappears and the new setting appears under Touch Switch Delay.
