<strong>6100CR</strong> <strong>Refrigerated</strong> <strong>Sampler</strong><br />
Section 1 Introduction<br />
sampler previously detected a fault in the tower, it will test the<br />
tower before it rotates the rack. The same will occur if the<br />
sampler previously detected a fault in the valve actuator, and the<br />
valve actuator must be returned to the normal position if it is<br />
not. Also, if the needle is not fully raised, the sampler will raise it<br />
before rotating the rack. The sampler raises the needle and<br />
returns the valve actuator to the normal position so they will not<br />
interfere with the rotation of the rack. Rack Reset will not have<br />
an effect when the sampler is in the running state.<br />
1.4.11 Manual Purge Pressing the Manual Purge key when the sampler is in the<br />
standby state will bring up the following screen:<br />
MANUAL PURGE<br />
STRAINER PRE-COOLER<br />
Selecting strainer will cause the sampler to open the flow valve<br />
so liquid will flow from the sample source through the strainer<br />
and valve. The liquid will be diverted by the valve and will not go<br />
through the sample pre-cooler or the actual bottle-filling mechanism,<br />
but will flow out through the bypass drain line. The flow<br />
can be stopped by pressing the ON/OFF key, or the Clear/Exit<br />
key. The Purge will also be stopped after a fifteen minute<br />
time-out. This function is useful for checking out the operation of<br />
the system, as well as purging air from the system after the<br />
strainer housing has been opened for cleaning.<br />
Similarly, selecting PRE-COOLER will cause the sampler to open<br />
the valve so the liquid will flow through the strainer, pre-cooler<br />
and the needle mechanism that fills the sample collection bottles.<br />
None will flow through the bypass. It exits the system through<br />
the sample overflow drain line. This selection does not cause the<br />
sampler to open a sample vial or put the sampling needle mechanism<br />
into a sample vial.<br />
Therefore, no liquid is introduced into a vial and no vials are contaminated<br />
by this operation. This operation is useful to verify<br />
that the system is functional, and that the valves open properly<br />
so the liquid can flow through the system. The operation is also<br />
useful to purge air from the pre-cooler upon initial installation<br />
and if it is drained during subsequent maintenance operations.<br />
The Manual Purge selections can also be useful if the sampler is<br />
not to be used for some period of time and it is desired to flush<br />
the system with clean water. If the inlet line is disconnected from<br />
the sample source and connected to clean water, these selections<br />
will make the sampler open the valves so clean water can flow<br />
through the system.<br />
1.4.12 Manual Sample This key allows you to take a sample any time the <strong>6100CR</strong> is in<br />
Standby, but it will not do manual sample within a running<br />
program. When you press this key, the unit will place a sample in<br />
the next bottle.<br />
