4.7 Sealing Arrangement in Prometer 100 – W
The meter incorporates sealing bars and screws with through-holes, through which traditional lead/wire seals
can be inserted. When utilized, these lead/wire seals can help prevent unauthorized personnel from gaining
access to meter internals or to button under the cover. The sealing provision in Prometer 100-W is as follows:
• The front cover can be sealed through the two sealing points under the terminal cover.
• The secondary terminal cover can be sealed through a sealing point.
• The extended terminal cover can be sealed through the two sealing points.
• The top cover can be sealed through the two sealing points.
• The 1107 optical communication port can be sealed using rotational seal.

4.8 Pulse Inputs and Outputs
The product support multiple pulse inputs and outputs. A maximum of eight pulse outputs (for Prometer 100-R)
and seven pulse outputs (for Prometer 100-W); and four configurable pulse input/ output can be provided as per
the specification agreed at the time of order.
Two pulse outputs (3 and 4 in case of Prometer 100-R / 2 and 3 in case of Prometer 100-W, refer to Figure 10
and Figure 12 for details) are linked to two pulse output LEDs indication as available on front side of meter so
that user can have a visualisation sort of feature by physically seeing the LEDs. The pulse output 3 (in case of
Prometer 100-R) / 2 (in case of Prometer 100-W) is linked to pulse output LED 1 and the pulse output 4 (in case
of Prometer 100-R) / 3 (in case of Prometer 100-W) is linked to pulse output LED 2. The Pulse Output LEDs can
be configured through M-Cubed 100 either at factory or in field. One pulse input can be used for time
synchronization application.
Configurable pulse input/output rating: 24 to 240 V AC/DC. Isolation will be available for each individual
input/output.
Pulse output rating: 24 to 40 V DC or 48 to 240 V AC/DC @ 100 mA (Pulse outputs will have volt free contact).
The only one rating will be applicable for entire block (each containing four outputs) and so isolation available
will be for entire block. The outputs are of solid-state type and when the meter is turned off, they are open.
