5 Start-up of Operation
5.1 Installation Instructions
Please read the installation instructions carefully and observe all steps when installing the device. If you do
not adhere to the installation instructions, there can be functional errors, or the required AMV guidelines may
be violated, or the EC conformity is lost.
Before connecting the device and starting operation, please make sure that the operating voltage and the
required operating voltage conditions of the device match those on site (see type label and technical data).
Take the respective measures if necessary.
The device will be powered by a separate power line.
This operating manual does not list all regulations and standards etc. which have to be observed when oper-
ating the device in conjunction with larger systems. These regulations and standards etc. have to be gath-
ered and observed by the operator of the device for the individual operation.
5.2 Start-up
Check the following before starting to operate the device:
Do the type label data match the data of your order?
The supply voltage has to be identical with the voltage information on the type label.
The nominal power of the connected consumer will not exceed the power indication on the type label
(ohmic load).

6.1.1 Connection of Device (see Fig. 2.0)
1. Connect main power cable, foot switch and air hose to back of device. Make sure that the incoming air
pressure is at 70 psi (4.8 bar) or more.
2. Press ON/OFF button (1) to turn on the device.
3. Connect valve air hose to connection A.
IMPORTANT!
The pressure in connection A can be controlled through the setting of the low pressure,
but it will not be controlled by the compressed air controller in the device. It will supply
the identical pressure as the incoming pressure. The pressure in connection B is con-
trolled separately and is not related to the setting of the low pressure.
4. Press mode button (2) and button "Set" (3) at the same time until "VALVE" is displayed in the upper
right corner of the display, as shown in Fig. 3.0.

vate the time-controlled dosing cycle.
22. If the device is in "INTERRUPT" mode (step-operation), push foot switch and hold until dosing cycle
has finished. Let foot switch go in order to interrupt the dosing cycle and push again in order to reacti-
vate.
6.4.5 Setting the Repeat Function for Counter of Encoder:
The preset maximum value for the counter of the Encoder is set to 60,000. However, there is also an ITER-
ATION FUNCTION („Itr“) which can be used to increase the dispensing duration up to four times (240.000)
without interruption.

this step to change units back to "psi".
4. Hold the “Set” button (3) for two seconds to exit the Setup-display.
6.7 Low Pressure Setting (see Fig. 9.0)
The low pressure value has been pre-set at the factory to 70 psi (4.8 bar). When the pressure falls below 70
psi (4.8 bar) the device will not operate anymore. Follow the below steps to change the settings for the low
pressure:
1. Set the dispensing cycle to “TIMED MODE”.
2. Hold the “Set” button (3) for two seconds to change into the Setup-display.
3. Press (+) and (-) button at the same time. The setting for low pressure appears in the display as shown
in Fig. 6.0.

7 Operation
7.1 General Information
This device will only be operated when all safety-relevant equipment is constantly operating and active and
will not be turned off during operation or altered in its designated function.
8 I/O Configuration and Feedback for End of Cycle
Upon completion of a dispense cycle, an open collector circuit closes and remains closed until the next
dispense cycle. This circuit can be used to signal back to a host computer, start another device in sequence,
or drive any other operations that need to be tied to the completion of the dispense cycle. Upon closure, (end
of dispense cycle), power from an external source is allowed to pass through the circuit to operate a 5 to 24
VDC load. Power consumption must not exceed 250 mA. The load could be a relay, solenoid, counter, LED,
or any device that will operate within a 5 to 24 VDC range and a maximum of 250 mA.
Note:
At the end of each cycle, pin 3 will be grounded. Please make sure the external device (your machine
that controls the dispenser/controller) has the same ground as the 97TS500R controller.
To initiate a dispense cycle with Voltage
During Cycle = GROUND
End of Cycle = OPEN
Low Pressure Alarm On = GROUND
Low Pressure Alarm OFF = OPEN
To initiate a dispense cycle with contact closure
Chassis Ground
PIN 7,8 and 9 = available
