PNEG-2175CE
CE Compliant Sampler - Model GCE 45 and GCE 90
Configuring the Controls
The Sample Sentinel controls can be configured in 2 ways:
1. Setting the sample period
2. Setting the auto-reverse time
Setting the Sample Period
The sample period is set at the programmer located on the panel door. (See Ref #8
The precise method of setting will depend on the type of timer used and specific instructions will be
provided with the controller.
IMPORTANT:
Do not set the sample frequency (cycle time) lower than 1 minute (60 per hour). This can
cause short cycling of the sampler motor and result in potential damage.
IMPORTANT:
Do not set the ON time any less than 0.5 seconds. This can result in the start signal not
being recognized by the controller.
Setting the Auto-Reverse Time
Auto-reverse is a safety feature built into the control to detect potential blockage or damage to the sampler,
resulting in it not being able to complete the traverse from left to right (or vice-versa). In this situation the
sampler will stop and reverse back to the starting position. The auto-reverse time is dictated by the size
of the sampler, and should be in accordance with table below:
