GF Signet 9900-1BC Produktanleitung Seite 4

Modules
• The Indicator LEDs on the front panel of
the 9900-1BC show the status of Open
Collector (relay 1) and relays 2 and 3.
• Hysteresis and time delay are
adjustable for each relay.
Switching active loads (usually inductive)
can cause contact arcing suffi cient to
damage the relays. The RC Filter Kit
or "snubber" (part number 3-8050.396)
is available as an accessory to reduce
or eliminate these damaging effects.
Recommended for inductive loads
greater than 50 VAC (remote relays,
solenoids, pumps, etc.).
4 9900-1BC Batch Controller Manual
CAUTION:
Batch Module
Convert a 9900 Transmitter (Generation II
or later) to a Batch Controller by plugging
in a Batch Module (3-9900.397).
Optional Module Wiring:
• Wire an external button or keypad
(customer supplied) to stop, start or
resume a batch remotely.
• Wire an external input that can inhibit
a batch from starting.
CAUTION:
Avoid Electrostatic Discharge (ESD)
To remove modules:
1) Remove power from the 9900
2) Remove the Relay module
3) Loosen bottom screw of Batch module
4) Carefully grip and squeeze the tabs
at the top of the module to release
5) Pull module away from the unit
6) Do not bend the connecting pins
Relay Module
In addition to the Open Collector output
in the 9900 base unit, the 9900-1BC
has a Relay Module which adds two
programmable dry-contact relays. The
Open Collector output in the base unit
uses the Relay 1 setting in the menus.
The Relay Module is assigned to
relays 2 and 3 in the menus.
Dry-contact relays are electromechanical
switches with a moving contact armature.
They are suitable for many general-
purpose applications, AC or DC, including
AC loads up to 250 V. Install RC Filter
Kits, 3-8050.396, on relays used to switch
motor or inductive loads.
• Two SPDT dry-contact relay inputs
• User programmable
• 250 V, 5 A maximum resistive
loading (AC).
• Can switch line voltage
(typically 120 to 240 VAC)
• Can switch DC voltage
(< 30 VDC @ 5A)
• Larger voltage and current ratings than
Open Collector outputs
(30 VDC, 50 mA maximum)
