4.4 Pacing Non-Isco
Equipment
For applications requiring the conversion of the flow meter’s flow
proportional output signal to a fixed duration contact closure,
Teledyne Isco offers the Type ‘E’ Interface.
Figure 4-1 Type ‘E’ Interface for pacing non-Isco equipment
To allow connection to a second device simultaneously, you must
connect using the special Isco Y cable, part #60-5314-278. A con-
nected sampler must have its own external power. NEVER
connect the sampler and flow meter to the same power source.
CAUTION
Do not use the standard Isco Y cable (60-3704-081) with the
Type ‘E’ Interface. This cable is designed for Isco sampler con-
nection only.
Use of this device requires a factory modification to the flow
meter. If you are connecting the Type ‘E’ Interface to a previously
purchased flow meter, prepare the unit by performing the steps
described in this section, or contact the factory to return the unit
for modification by Technical Service.
DANGER
Risk of electrocution. Disconnect the flow meter
from power before performing any modification
or repair.
