Relay Modules CRF-300-6 Installation & Wiring
7.4 CRF-300-6 Installation & Wiring
7.4.1 Cabinet Installation
This type of module is contained in either a BB-2 or BB-6 cabinet. The BB-2 can accommodate up to 2 modules and the BB-6, which
requires the CH-6 chassis, can accommodate up to 6 modules.
See the Installation Instructions provided with module for proper installation into cabinet.
7.4.2 Setting an SLC address for a CRF-300-6 Module
Each CRF-300-6 module can be set to one of 154 base addresses (01-154). The remaining module points are automatically assigned to
the next five higher SLC addresses. For example, if the base address is set to 28, the next five module points will be addressed to 29, 30,
31, 32 and 33.
DO NOT set the lowest address above 154 (45 for the MS-9050UD and ES-50X, 94 for the MS-9200, MS-9200UD, MS-9200UDLS,
and ES-200X), as the other module points will be assigned to nonexistent addresses.
7.4.3 Disabling Unused Module Addresses
A shunt is provided on the circuit board to disable a maximum of three (3) unused module addresses. If two
module addresses are disabled, the lowest four addresses will be functional, while the highest two will be
disabled. For example, if the shunt is placed on ‘TWO’ and the base address is set to 28, the module
addresses will be assigned to 28, 29, 30 and 31.
To disable addresses, remove the shunt from its storage location and securely place it onto the desired set of
pins. See illustration.
7.4.4 Wiring a CRF-300-6 Module (Form-C Relay)
The figure below shows a CRF-300-6 module wired to the Control Panel.
NOTE: The MS-9050UD and ES-50Xcan support addresses 01 - 50. The MS-9200,MS-9200UD,MS-9200UDLS, and ES-200X can
support module addresses of 01 - 99. The MS-9600, MS-9600LS, and MS-9600UDLS can support module addresses 01 - 159. To set an
SLC address, use a common screwdriver to adjust the rotary switches on the module to the desired address. See Figure 6.4 on page 47.
For use with an MS-9600, MS-9600LS, MS-9600LSC, and MS-9600UDLS, remove the stop on the upper rotary switch.
