4.2 Pulse Input
In the counter mode, the Z-65/6.1 is designed to
energize the sample pump solenoid once the
preset number of pulses are received. The rate
at which this occurs is a function of operator
input as well as the turbine flow meter or other
device that inputs pulses per volume metered.
The two 10 position switches on the Z-65/6.1
are used to set the number of input pulses the
counter will count before activating the solenoid
output. The number of times the solenoid
output is activated is recorded by the onboard
LCD stroke indicator. In this mode of
operation, the Z-65/6.1 counter operates as a
dividing counter. The PIM-100 Pulse Input
Module is a low power device designed to
interface between a DynaPak Z-65 controller
and a magnetic pickup input. The PIM-100
provides fixed width logic level output pulses
used to drive the count input of a Z-65 controller
at a rate determined by a user configurable
divisor. The switch settable divisor, ranging
from 1 to 524,287, divides the input pulses from
a turbine flow meter by the cumulative number
represented by the “ON” divisor switches.
Actual programming of these values will be
discussed in section 8. An input adjustment
potentiometer is provided on the PIM-100 to
allow adjusting the input sensitivity.

CAUTION:
Incorrect operation of valves (over tightening) can result in damage to the valve
components (isolation valve bonnet assembly) which might result in the valve
stem being screwed out of the probe body. This of course results in product at
pipeline pressure being vented continually through this port until this section of the
pipeline is shut in. Be aware of the following procedures and information.
· DynaPak valves are of soft seat design and should only be closed
or opened with fingers. No wrenches should ever be used.
·If a valve will not seal off with finger tight operation the valve should
have maintenance performed to allow proper operation of the valve.
