[ ] … Assignment to the block diagram

The ramp generator [4] output signal is forwarded to the summing amplifier [5] as current command value. Here, a voltage of +6 V corresponds to a command value of 100 %.

In the summing amplifier [5], the output signals of the characteristic curve generators [6 or 7] are added to the command value (can be selected by means of DIL switches  depending on the valve to be controlled). The current command value can be filtered by means of a connectible low pass. The current output stage [9] is controlled using the current controller [8]. In the current controller, the current command value is moreover modulated with the clock generator signal [10] (frequency can be programmed using the DIL switch). In the valve solenoid, the clocked actual current value acts like a constant current with superimposed dither signal. Type VT-VSPA1-1 has measuring sockets for the internal command value and the actual value.

The following is true for the command value:+6 V ≙ 100 %

The following is true for the actual value: 1 mV ≙ 1 mA

The “ready for operation” signal is output and the “H2” LED on the front plate (with VSPA1-1) or the “H2” LED (with VSPA1K-1) is illuminated if:

there is no short-circuit of the solenoid conductors and no overload of the output stage,

a command value is available (cable break detection),

there is no cable break of the solenoid conductor.

In case of a fault, the following applies:

The command value input 2 is a differential input [1] (0 to +10 V). By means of DIL switches , it can be configured as current input (4 to 20 mA or 0 to 20 mA). If the command value is specified by external electronics with a different reference potential (e. g. by a PLC), this input has to be used. When disconnecting or connecting the command value voltage, it has to be ensured that both signal lines are in each case separated from or connected with the input.

Before they are forwarded, both command values are summed up [2] and then reach a potentiometer [3] accessible at the front plate of the card which acts as attenuator and thus limits the maximum command value.

The downstream ramp generator [4] generates a ramp-shaped output signal from a given stepped input signal. The time constant of this signal can be separately adjusted for the upwards and downwards direction by means of two potentiometers. The specified ramp time refers to a command value step of 100 % and may be approx. 1  s or 5  s, depending on the setting by means of a DIL switch. If a command value step of less than 100 % is switched to the ramp generator input or if the attenuator [3] is effective, the ramp time will be correspondingly shorter.

To type VT-VSPA1-1, the following applies: By means of the external “Ramp Up/Down off” contacts, the upwards and downwards ramp times can be separately set to their minimum value (approx. 30 ms).

To type VT-VSPA1K-1, the following applies: By means of the external “Ramp off” contact, the upwards and downwards ramp times can be set to their minimum value (approx. 30 ms) together.

Notice:

If an external command value potentiometer is used, the internal potentiometer “Gw” [3] must be set to maximum or to the desired maximum pressure.

The command value voltage is specified at the command value input 1 either directly or via an external command value potentiometer by means of the regulated voltage +9 V of the power supply unit [14]. The reference potential for command value 1 is M0 (measurement zero). To this input, the following applies: +9 V ≙ +100 %.

It has to be ensured before commissioning of the amplifiers that the DIL switches on the printed circuit board are set according to the relevant application.

In the condition as supplied, the parameters are set as follows:
max. ramp time = 5 s, pilot current = 100 mA, max. output current = 800 mA, clock frequency = 200 Hz.

The amplifier card may only be assembled when de-energized.

No connectors with free-wheeling diodes or LED displays must be used for solenoid connection.

Only carry out measurements at the card using instruments Ri > 100 kΩ.

Measurement zero (M0) is increased by +9 V compared to 0 V operating voltage and not isolated, i.e. –9 V regulated voltage  0 V operating voltage. Thus, do not connect measurement zero (M0) to 0 V operating voltage.

For switching command values, relays with gold-plated contacts have to be used (low voltages, low currents).

Always shield command value lines, connect shielding to earth on the card-side, other side open. The card has to be connected to the earth via terminal 6 or 8. If no system earth exists, connect 0 V operating voltage.

Recommendation:
Also shield the solenoid conductors. For solenoid conductors up to 50 m in length, use the line type LiYCY 1.5 mm2. For greater lengths, please contact us.

The distance to aerial lines, radios, and radar systems has to be at least 1 m.

Do not lay solenoid conductors and signal lines near power lines.

The charging power of the smoothing capacitor on the card requires the pre-fuses to be of a slow-blowing characteristic.

If the differential input is used, both inputs must always be connected or disconnected simultaneously.

Troubleshooting

If the amplifier cards do not function, the following steps are required for troubleshooting:

Operating voltage available?
Measurement of contacts 24(ac) against 18(ac)

Fuse on card faulty?

Internal ±9 V operating voltage available on the card?

If the internal command value potentiometers are used, is the bridge from 10(ac) to 12(ac) available?

Is the external potentiometer correctly connected?

Is the differential input connected correctly?
Check:reference potential at 30(ac), 0 to +10 V at 28(ac)

Is the solenoid correctly connected?
If the card is removed, a resistance of approx. 20 Ω to 30 Ω or 5 Ω to 8 Ω has to be measurable between contacts 22(ac) and 20(ac) depending on the valve type.

The amendment of the connection designations in brackets only applies to type VT-VSPA1-1.

Notice:

The output stage switches off at overtemperature (e. g. due to overload). This error is displayed by the “H2” LED going out.

In case of cable break of input "4 to 20  mA”, the “ready for operation” signal is reset and the “H2” LED will go out as well.

From component series 11, the following applies:
In case of short-circuit or cable break of the solenoid conductor, the ready for operation output will clock and the “H2” LED will flash with a frequency of 0.5 to 2 Hz as soon as the command value is simultaneously > 2 %.
