3.2 Restrictions
The installation location must have appropriate supply power available for the instrument
(i.e., 19.5 to 28.5 VDC or 24 VAC)
. This ultimately determines the distance the instrument can
be mounted from the controller or power supply.
3.3 Mechanical Installation
WARNING:
DO NOT allow the lid / sensor to hang from the ribbon cable. Failure
to comply may result in damage to the product.
1. Using the provided hardware, securely mount the MGS-400 gas detector according to
the product dimensions, maximum wiring lengths and following considerations:
a. Environment: the full range of environmental conditions when selecting a
location.
b. Application: the specifics of the application
(possible leaks, air movement / draft,
etc.)
when selecting a location.
c. Accessibility: the degree of accessibility required for maintenance purposes when
selecting a location.
d. Target Gas: the specific gravity of the target gas when selecting the height of the
instrument.
2.
Using a 5/32″
(4 mm)
hex key / allen wrench
(not included)
remove the lid and
disconnect the ribbon cable from the base.
3. Set the lid and rubber gasket
(IP66-rated enclosures only)
aside to be reinstalled later.
3.4 Electrical Installation
3.4.1 Preparations
IMPORTANT:
If analog output is configured for 4 to 20 mA output, ensure that
the current loop is connected to a sinking current loop monitor before powering
on the instrument. Otherwise, a fault may be displayed indicating an open loop
condition. If analog output is unused, ensure it is configured as a voltage output
(default: 1-5V)
to prevent an open loop fault condition. The analog output is
designed as sourcing.
CAUTION:
Ensure wiring for relays and connections for sensor
(s)
are made
before applying power.
CAUTION:
This product uses semiconductors which can be damaged by
electrostatic discharge
(ESD)
. When handling the printed circuit boards
(PCBs)
,
observe proper ESD precautions so that the electronics are not damaged.
