Kohler 20-3250 kW manual Wireless Monitor

6.1.18 Wireless Monitor

The wireless monitor system has two components: a wireless monitor unit and a website. The monitor unit transmits messages in response to signals received from the equipment controller and notifies designated recipients of selected operating conditions. The website monitors these messages.

There are three monitor models: GM23409-KP1 for use with hardwire inputs; GM23409-KP2 for use with a 550 controller using Modbusr communication; and GM23409-KP3 for use with a 550 controller using hardwire inputs that require a customer interface board.

Note: The 550 controller supports only one connection for Modbusr communication. If the controller’s RS-485 connection is already used for Modbusr communication with other equipment, use wireless monitor model GM23409-KP1 or -KP3 with hardwire inputs through a customer connection board for monitoring.

Typical messages might include:

DOvercrank

DLow oil pressure

DOverspeed

DCommon fault

At the website, the user configures which individuals will receive messages regarding selected operating conditions and the message delivery method. Delivery methods include pagers (alphanumeric, numeric), fax, XML, e-mail, PCS, or telephone (voice delivery). Each message sent will contain the condition that generated the transmission and also the make, model, and location of the equipment. Up to 40 messages each day can be delivered. Single or multiple messages can be sent to selected recipients via multiple delivery methods. More than one delivery method can be used for each recipient.

The wireless monitor is powered by the equipment power source or by the generator set and constantly monitors the inputs. When an input is triggered, the wireless monitor sends the condition over the North American AMPS (advanced mobile phone system). An operations center server receives the transmission and forwards the message to the selected recipients according to the configured delivery method.

Every 24 hours, the wireless monitor also sends information about itself and the system it is monitoring.

This heartbeat transmission tells the Kohler center that the wireless monitor is properly functioning, powered, and able to generate messages. If a device fails to report a nightly heartbeat for more than a day, the system sends a Unit Failed to Report Heartbeat alarm message to the website.

Generator set run times and the number of cycles are reported. Models GM23409-KP1 and -KP3 accumulate run times over a 24-hour period and report the run times with the heartbeat message. Model GM23409-KP2 (for the 550 controller only) reports the total accumulated run time and the total number of starts. Run times for model GM23409-KP2 are also totaled using the Control Panel function and can be updated upon request.

Upon power loss, a rechargeable battery powers the wireless monitor. The monitor continues to transmit messages for 15 minutes, then transmits a loss of power signal and enters the sleep mode. The sleep mode can last up to 18 hours, until the battery completely discharges or power is restored. The wireless monitor continues to send scheduled heartbeat messages during the sleep mode until the battery discharges completely.
