ET the sampler takes samples only while the liquid is touching the probe assembly When the liquid level rises to the probe assembly the 1640 actuates the sampler The sampler will continue taking samples only as long as the liquid touches the stainless steel ring If the liquid level recedes the sampler will be inhibited until the liquid level again rises to the probe assembly If the liquid level recedes while the sampler is taking a sample it will finish taking the sample before shutting off The TOGGLE RESET switch selection is also used to reset the Liquid Level Actuator You must configure the sampler to respond to the actuator Infor mation on programming the sampler for use with the actuator can be found in the discussion ofthe ENABLE PIN or SAMPLER ENABLE configure option in the sampler s manual All Isco sam plers can be used in either the Time or Flow mode when used in conjunction with the 1640 If the Flow mode is used a Y connect cable Isco part 60 3004 019 will be necessary to connect both the 1640 and the flow meter to the FLOW METER port on the sampler To program the sampler and 1640 when the actuator is set to LATCH the following set of instructions is recommended 1 Program the sampler for the time interval or number of flow pulses between samples following the instructions given in the sampler s manual 2 Momentarily set the 1640 CONTROL switch to the TOG GLE RESET position to reset the actuator 3
6. Set the CONTROL switch to the LATCH position When first actuated the sampler will immediately take a sample if the time period from when the sampler and actuator were turned on to when the liquid level reaches the probe assembly is greater than one time period between samples as programmed on the sampler The sampler will then return to its prescribed time base and take samples at the programmed time intervals If after the sampler and 1640 have been turned on the liquid level rises to the probe before one time interval between samples as programmed on the sampler has passed the sampler will wait until the end of the first time interval to take the first sample Thereafter it will take samples as programmed For example The 1640 is set to LATCH and the sampler is turned on at 4 00 The sampler is programmed to take a sample 2 3 1640 Liquid Level Actuator Section 2 Operating Procedures 2 4 2 4 2 ProgrammingTOGGLE Operation every hour on the hour At 6 20 more than one time interval between samples has passed the liquid level rises to the probe and the 1640 actuates the sampler The sampler then takes the first sample at 6 20 the second at 7 00 the third at 8 00 etc and continues taking samples every hour until it completes it s entire program However if the sampler is turned on at 4 00 and the liquid level rises to the probe at 4 20 less than one time interval between samples has passed then the sampler will take t
