General Information

H-100 Control Panel Technical Manual

For this example, HTS number 1 is now enabled. If HTS #1 is not connected or if the HTS is not #1, there will be a communications error indicated.

In an H-100 Control Panel system with HTS switches, the annunciator will indicate Line Power or Generator Power based on the status reported from the selected HTS. The selected HTS is the HTS number that was selected using the H-100 control front panel. The number is selected on either of the Exercise/HTS pages (3-4) or (4-4). The two designated H-100 con- trol panel inputs Input #7 and Input #8 are free to be used for other functions and will not affect the annunciator as long as at least one HTS is connected and enabled.

NEW GENERATION GENLINK (NGG)

COMMUNICATIONS

There are 2 ports on the H-100 Control Panel, an RS-232 port and an RS-485. Each port can be recon- figured as to its function, however there can only be one master Modbus port. All ports can have their baud rate, parity and stop bits changed. For Modbus ports, the address can also be changed via GenLink, but each address in a connected system must be unique. Normally the RS-232 port will be configured as a Modbus slave to communicate with GenLink and the optional Modem. The RS-485 port will act as a master for connection to up to two remote annuncia- tors/remote relay panels and up to four HTSs. The RS-485 port can be reconfigured via GenLink to be a deep diagnostic port.

REMOTE ANNUNCIATOR CONNECTION (OPTION)

The H-100 Control panel RS-485 port is normally configured as Modbus Master, 4800 baud, no parity, and two stop bits. This is the required configuration for the remote annunciator. However, the remote annunciator is often shipped configured as a Modbus Master (active mode). A wire jumper must be added in the remote annunciator to configure it as the Modbus Slave (passive mode). A total of up to two remote annunciators and remote relay panels can be attached to the RS-485 bus. See the remote annun- ciator/relay panel manual for details.

In an H-100 Control Panel system without HTS switches, the annunciator will indicate Line Power or Generator Power based on two designated H-100 con- trol panel spare inputs Input #7 (Also labeled DI3) and Input #8 (Also labeled DI4). These inputs can be used for other functions as desired, but will always operate the annunciator lights. Input #7 should be connected to Line Power indication. Input #8 should be connected to Generator Power indication.

An all new version of GenLink has been released for support of the H-100 Control Panel. It uses the industry standard Modbus protocol for communica- tions and acts as a Modbus master. GenLink runs on PC platforms running Windows 98 (but will not support future Internet applications), Windows NT 4.0, Windows 200 and XP. We recommend an Intel Pentium 4 processor (1.0gHz+) with a minimum 64MB memory and 20GB hard drive. plus 56k Zonet PCMCIA based modem. For details about GenLink, refer to the New Generation GenLink man- ual. Addtional features include:

GENLINK RELAY CONTROL

There is a “Radio Button” displayed on the main GenLink display screen. This button will set or reset output function 106 which in turn can be made to drive a relay or any combination of things (via the ILC). The function can be renamed and this new name will appear above the radio button.

SET ENGINE HOURS

In the event that a controller has to be replaced, the engine hours on the new controller can be set to match the controller it is replacing. This can only be done at the factory.
