Sentry Industries 5000 사용자 설명서

 

Model 5392-00 Individual Relay Panel extends Sentry 
low alarm and high alarm capability by providing 
individual single pole double throw (SPDT) dry contacts 
for each alarm level for each module.  The panel is 
designed to be installed as follows: 

• 

Rack or Chassis Controllers:  Mounted on 
stand-offs on the connector panel of the 
controller, or installed on the back of spare slots 
in 19” instrument shelf Model 5331-00. 

• 

Wall Mount:  Supplied pre-installed on a 
separate wall mounting panel 

• 

NEMA 4X Enclosure:  Mounted on swinging 
connector panel beside the display panel.  
(When other options are installed in the 
enclosure, the Individual Relay panel may be 
installed inside the swinging panel) 

The panel connects to the Sentry controller via a ribbon 
cable. 

Individual Relay Panels supplied with original Sentry 
shipments are factory pre-assembled with the controller.  
For NEMA enclosures, the panel is fully installed prior to 
shipment.  For other controllers minor final assembly is 
described below. 

Individual Relay Panels supplied as add-on to original 
Sentry controllers require that the connector panel of the 
controller be removed so that threaded stand-offs 
(supplied) can be installed onto the four corners of the 
panel. 

The following are instructions for final installation and 
wiring of the Individual Relay panel: 

1.  Perform normal installation of the Sentry 

controller and modules and perform function 
checks of the basic system. 

2.  Power down the system. 

3.  Plug the Individual Relay Panel ribbon cable 

into the connector on the controller. 

4.  Mount the panel on the four stand-offs on the 

connector panel of the controller [not required 
for NEMA enclosures]. 

5.  Make the necessary connections to the high and 

low relays for each of the modules as required 
for the particular application. Note that these are 
dry contact relays and that power must be 
connected from an external source. 

Figure 8-2 shows the location of the sixteen relays which 
are marked as "high" and "low" alarms for the respective 
modules. 

When any module connected to the controller is in alarm 
it's respective relay will be energized. 

To operate alarms or other auxiliary equipment connect to 
the required relays according to the module number. 

Several logic configurations are available: 

• 

The user can configure each alarm as latching or 
non-latching via the 

 menu 

activity. 

• 

A factory option available with the 
Enhancement Package allows all high, or all low 
alarms, or both, to be configured for alarm 
acknowledge when latched. 

• 

A factory option available with the 
Enhancement Package allows alarm  states to be 
combined into zones and voting groups for 
activation of individual relays. 

Table  8-2 is helpful for determining the relay actions 
which will occur under various alarm conditions based on 
the user’s configuration. 

To use the table: 

1.  Select one of the nine possible combinations of high 

and low alarm relay configurations in the top two 
lines across the table. 

2.  Select one main block of the three alarm status 

scenarios from the left column. 

3.  Trace the relay and LED  status conditions for each 

change in alarm status. 

4.  Where there are secondary columns, move to the 

secondary columns at any point by pressing Alarm 
Reset, Enter.
