INPUT : Jumper Settings
The Input type is user configurable and thus requires, besides parameter selections,
proper jumper-settings prior to electrical
connections. The jumper settings are provided in the form of Pins & Shorting-Link arrangements on the CPU PCB towards the
rear end as shown in Figure 9.3.
The Jumper setting marked A is for Input configuration. (Jumper settings marked B & C are unused.) For DC Linear Current
Inputs (0-20mA or 4-20mA), short the Pins using Shorting-Link. For all other Input types, keep the Shorting-Link parked
leaving the Pins open.
MOUNTING PLUG-IN MODULES
The indicator supports up to 3 plug-in modules, viz.
Output-2 Module
(Relay/SSR),
Output-3 Module
(Relay/SSR) and
Option
Module
(RS485 Serial Port or Remote Alarm Acknowledgment). These modules are either pre-fitted while the indicator is
shipped from the factory or can be fitted by the user later.
All 3 plug-in modules are provided with female socket that directly fits into the corresponding male plug provided on either
Power-supply PCB or CPU PCB. The
Output-2
and
Option
Modules fit into plugs provided on Power-supply PCB whereas the
Output-3
Module fits into plug provided on the CPU PCB
OUTPUT-2 & OUTPUT-3 : Modules and Jumper Settings
The
Output-2
and
Output-3
Modules are identical and, thus, can be fitted interchangeably in Output-2 or Output-3 positions.
These modules can be configured for either Relay or SSR output through proper jumper selection. Two jumper settings A and
B, as shown in Figure 9.4, are required for Relay or SSR selection. Refer Table 9.1 for appropriate jumper setting positions.
