SELECTING THE VALVE TYPES
When setting a valve, the operator generally must ensure that no command
value and no enable is applied to the VT-MSPAx-2X!
The desired valve type has to be selected by means of the two rotary switches, see
item 4. The left-hand rotary switch sets the tens place, the right-hand rotary switch
the units place of the item. While you make the settings, test jack “v“ outputs the
selected rotary switch position as a voltage value in 100-mV increments.
The following valve types are available.

If no valve type is selected, the LEDs signal the status shown on the left. The
yellow LEDs rotate clockwise in pairs.
The ready LED
blinks red/green, if the valve number saved last and the
current rotary switch position do not match!
The amplifier is active and utilizes the parameters of the valve type saved last.
Remedy:
If you wish to change the valve, remove the command value and the enable,
press key
[Set]
> 1 sec and accept the new valve type.
If the rotary switch position was changed accidentally, reset it to the original
valve number.
→ The ready LED
is lit green.
In both cases, check the actually connected valve!
Whenever a valve is changed, all editable parameters are reset to factory
settings!
