Balance Connection; Personal Computer Connection; Footswitch Or Dispensing Wand Connection; Relay Outputs - Masterflex Digi-Staltic L/S 77310-00 Manual De Operación

If the voltage selection switch is set to the incorrect voltage, refer
to Figure 5 and set the switch to match the voltage of your AC
source. Slide the switch so the correct voltage is displayed.
Ensure that the AC outlet is grounded and meets all local and
national codes. The use of ground-fault interrupted AC power is
recommended because of liquid handling. Use the supplied power
cord for each pump in the system. Refer to Figure 4, and attach
the female plug to the connector on the back of the pump drive.
Plug the male connector into a properly grounded AC outlet.

BALANCE CONNECTION

In order to operate the dispense program with a balance, a
compatible balance must be connected to the control console.
The DIGI-STALTIC provides communication to the balance
through a nine-pin male RS-232 DTE port on the back of the
control console. Refer to APPENDIX A — BALANCE
CONNECTION for a list of compatible balances and a description
of the RS-232 connections.
WARNING: Ensure that all pump drives and the balance are disconnected from the power source.
1. Make sure that all power is disconnected.
2. Ensure that the balance is compatible with the dispenser and that the cable is constructed so that pin connections
are in accordance with Figure 16 in APPENDIX A — BALANCE CONNECTION.
3. Refer to Figure 4, and connect the balance to the connector labeled BALANCE on the back of the control console.
4. Tighten the two screws on the connector.

PERSONAL COMPUTER CONNECTION

The DIGI-STALTIC may be controlled by a personal computer using software shipped with the system. A serial port on
the computer connects to the RS-232 DCE port on the back of the control console. Refer to Figure 17 in APPENDIX B
— PC CONNECTION AND SOFTWARE INSTALLATION for pin connections and signals.

FOOTSWITCH OR DISPENSING WAND CONNECTION

In order to run a program with a footswitch or dispenser wand, the accessory must be connected.
WARNING: Ensure that the pump drive is disconnected from the power source.
1. Ensure that all power is disconnected.
2. Refer to Figure 4, and connect the DB-9 connector from the footswitch or dispenser wand to the nine-pin connector
on the back of the pump drive.
3. Tighten the two screws on the connector.

RELAY OUTPUTS

Each DIGI-STALTIC pump drive provides control to external apparatus through two drive relays. Normally open contacts
are open when the relay is off and closed when the relay turns on. Normally closed contacts are closed when the relay is
off and open when the relay turns on. Table 3 provides the three possible states for the relays for each type of program.
Connections are made to the relays at the DB-9 connector on the back of the pump drive.
