VSD2001 EEV Driver
(one-driven-two)
※SAFETY ATTENTION※
1. Do not turn on the power before completing the wiring, cut off the power before changing the wiring.
2. Although the electronic circuit inside this product has been protected to a certain extent, long-term operation
in a humid environment will still cause damage to components, so please avoid install and operate in
environments such as rain, moisture and with other liquids.
3. An output wire to be used for this product should be inflammable grade FV1 (v-1 grade or above).
4. Please avoid installing the product in a place where a strong magnetism, noise, severe vibration and impact
exist.
5. Please avoid using the product near a device generating strong high frequency noise (high frequency welding
machine, high-frequency sewing machine, high-frequency radiotelegraph, high capacity SCR controller)
6. Please confirm that the jumper caps and valve type parameters of the VSD2001 driver are set correctly, and
there is no error state which green and yellow lights flashing at the same time for EEV1 and EEV2 before use.

Note :
1. Cable wire range : 28 ~12 AWG (0.2 ~ 0.8 mm²).
2. Do not tun on the power before completing the wiring, cut off the power before changing the wiring.
3. Pay attention to not reverse the EEV connection. EEV1 with the analog signal 1 and the EEV 1
parameters.
4. Do not connect 24V- wire and GND wire together.
5. If you want to use 1 analog signal to control 2 x EEV in parallel, please connect the 0-10V signal on both
analog inputs. Check that the 0-10V supplier voltage doesn’t deform the signal.
