Sentry SBC Controller Original Instructions 7
Installation
Installation should be performed by qualied personnel in accordance with state/provincial and local codes and
procedures.
Mount the controller in a location that is easily accessible and within view of the sampler.
Mount the controller in a vibration-free location and have a qualied electrician wire the controller to the electrical
supply.
Surge suppression and ltering is recommended but not required.
Hard wire the controller to instrument-quality power using appropriate certied conduit, ttings, and wiring or
cable.
Use a suitable external over-current protection device, such as a fuse or circuit breaker (15 A), and disconnect device.
The over-current protection and disconnect devices shall be installed on both the hot (L) and neutral (N) leads.
The disconnect device shall be located near the equipment and marked with appropriate ON(|) OFF(O) markings as
specied by local codes.
When penetrating the controller enclosure, use tubes and ttings that maintain the environmental rating of the
enclosure.
Inputs
ÂNOTE
Inputs I3 through I7 are located on the Index Cabinet. Inputs H1 through H4 and A1 are eld-mounted devices. The signals are
processed in the Sentry SBC Controller.
I1. REMOTE ENABLE: External contact from customer which, when open, prohibits all operation of the sampler. If
not used, leave terminals TB2 1 and 2 wired together.
I2. REMOTE START: External contact from customer, using terminals TB2 3 and 4, which initiates sampling when in
REMOTE mode.
I3. SAMPLER PROX 1: Proximity sensor input. Used for control of MG and SA/E samplers.
I4. SAMPLER PROX 2 or IC Jar Sensor: Secondary proximity sensor input or proximity sensor used to sense level of
jar ll in the Indexing Cabinet.
I5. IC DOOR: Proximity sensor input conrming position of door on the Indexing Cabinet. Operation inhibited if
door is open.
I6. IC Carousel: Proximity sensor input conrming the position of the carousel of the Indexing Cabinet.
I7. IC Manual Pushbutton: Manual advance pushbutton for the Indexing Cabinet.
I8. Delay Start: Contact closure triggers a time delay. After delay timer expires, sampling will start.
H1. High Speed Counter: Flow counter input used for ow based sampling (10 kHz max frequrency; 100 µs min
pulse resolution).
H2. Digital or COUNTER Input: Extra digital input or high speed counter input available for future control
enhancements.
H3. Digital or COUNTER Input: Extra digital input or high speed counter input available for future control
enhancements.
H4. Product Backup Sensor: Proximity sensor input used for sample backup indication.
A1. 4-20 mA INPUT: Flow meter output used for ow based proportional sampling.

Operation
Quick Start
The rst time power is applied, the controller defaults to Quick Start. Quick Start leads the operator through the
controller set-up procedure step-by-step.
To access Quick Start on subsequent power-ups, press the Service key and select Quick Start.
Using the Controller Keys
System Keys
1. Soft Keys: The arrow keys on either side of the display correspond to keys programmed on the screen. The rim
surrounding the soft key shown on the display will be lled when the option is selected.
2. ESC: Returns to previous screen; ends editing session without accepting new value.
3. Arrow Keys: The up, down, right and left arrow keys located directly below the display are used to navigate menu
selections and change editable values.
4. ENTER: Accepts new values; selects menu options; enters editing mode.
5. Numbers: In editing mode, all of the function keys can be used to enter numbers, which are shown in gray on the
upper right hand corners of the keys
Sentry SBC Controller Original Instructions 9
Command Keys
1. AUTO: Places the controller in AUTO mode. This mode allows local operation of the controller.
2. Remote: Allows remote operation of the controller. Sampling starts when a contact from an external source is
closed. Continuous sampling occurs for as long as the contact is closed. Momentarily closing this contact will start
a single sample.
3. OFF: Takes the sampler out of REMOTE or AUTO mode; will reset the Batch counter.
4. Purge: If sampler has a purge/air eject option, this key manually operates the solenoid to purge the unit.
5. GRAB: Allows the operator to immediately collect a sample. Sampler must be in the Cycle/Retracted portion of the
sampling cycle or in the OFF state.
Menu Keys
1. MAIN: Main operating screen displays sampler position, current timer value, current mode, and Batch and IC count.
2. Setpoint: Lists all program setpoints.
3. Option: Menu of the available program options and routing to pertinent screens.
4. Service: Menu of service-related options such as I/O Status, Quick Start, Operation Sequence, Default settings, and
Cycle Counter.
5. Alarm: System alarm log.
10 Original Instructions Sentry Equipment Corp
Starting and Operating the Controller
After the sampler and controller are installed, timer setpoints must be veried or changed from the factory preset
values.
1. Press the Setpoint menu button to access the Setpoints menu screen.
2. The Setpoints menu screen lists all the setpoints available for adjustment.
3. Refer to the appropriate appendix for information on the setpoints for your sampler model.
Timers
ÂNOTE
Timers used depend on sampler type. See appendix appropriate to your sampler.
1. Extend or Sample time: Determines the time the sampler is in the process stream (max 600 sec).
2. Retract time: (not applicable to all samplers) Determines the duration the sample probe is retracted, allowing the
sample to be deposited into the sample container (max 600sec).
3. Cycle Time: Determines the time between samples (max 17:59:59).
4. Delay Time: (not applicable to all samplers) Determines the time before purge/air eject occurs (max 600 sec).
5. Purge Time: (not applicable to all samplers) Determines the time purge/air eject is active (max 600 sec).
6. Park Time: (not applicable to all samplers) Determines the time the sampler is in the Park position (max 17:59:59).
Modes of Operation
The controller operates in two modes, AUTO and REMOTE, with the capability to take a GRAB sample in either mode.
AUTO and REMOTE cannot be selected at the same time.
Auto Mode
Auto mode is the default mode of operation.
Press the AUTO key to place the controller in Auto mode.
All operating commands are initiated at the controller panel.
Refer to the appropriate appendix or the Service Menu of the controller for the sequence of operation specic to
your sampler model.
Remote Mode
Press the REMOTE key to place the controller in Remote mode.
Start and stop commands are initiated from a remote control system.
Sampling is started and stopped based on an external contact (Terminals TB2 3, 4).
– When the contact is closed, sampling starts.
– When the contact is removed, sampling stops.
– If contact is removed in the middle of a sampling cycle, the sampler completes the cycle and then stops.
– A momentary closure of the remote contact results in a single sample being taken.
