5.5 - Sensor input
See 5.3A, pins 1–6
The
Sensor Input
terminal can be wired to suit numerous input types. See Section 6 for input
wiring, or refer to the ToolBox help panel as you are confi guring the unit.
5.6 - Analogue output
(If installed)
See 5.3C, pins 9–10
If your model includes
Analogue Output
, wire it as shown (right).
The analogue output can be scaled to suit your application using the
ToolBox soft ware.
5.7 - Relay outputs
(If installed)
See 5.3F, pins 13–16
If your model includes
Relay Outputs
, wire them as shown (right). The
setpoints can be confi gured using ToolBox for a variety of alarm or con-
trol functions.
5.8 - User input
(If installed)
See 5.3E, pins 11–12
If your model includes
Relay Outputs
, then a
User Input
is also pro-
vided. This can be connected to a switch as shown, to perform manual
relay reset and latching functions. These options are fully confi gurable
using the ToolBox soft ware.
CAUTION
The User Input common is NOT isolated from the Sensor Input.
In order to preserve the safety of the meter application, the User
Input common must be suitably isolated from hazardous live earth
referenced voltages; or the User Input common must be at protec-
tive earth ground potential.
If not, hazardous live voltage may be present on the User Input
and the User Input common terminals. Appropriate considerations
must then be given to the potential of the User Input common
with respect to earth common.
