YSI Incorporated 7 5200 Recirculating System Monitor
Status Lights
The 6 status lights located on the front panel of the 5200 (see Figure 2-1 Front Panel) indicate whether a
system is operating within its preset limits or a control system has been activated.
Parameter Status Lights for Temperature, DO, pH, Conductivity and ORP are configured as follows:
OFF – parameter not enabled
GREEN – normal range
FLASHING GREEN – control mode (turns off when it crosses the original set point)
RED – alarm (turned off by pressing any key, except escape, and resolving the alarm condition)
The System Status LED is configured:
GREEN – normal operation
RED – battery back-up
Flash Memory Architecture
A key feature of the YSI 5200 is that it is designed using FLASH memory allowing software updates to
be easily accomplished. Refer to Section 9.1.5 Downloader (Upgrading Software) for instructions on
upgrading the software in the YSI 5200.
Powering the YSI 5200
Primary power for the YSI 5200 is either a wall mount power transformer providing 8.5 to 16 VDC at
700 mA or any power source providing voltage and current in the stated operating range. The YSI 5200
comes standard with a 12VDC 700 mA wall mount power supply. In addition, an optional 12VDC battery
backup input is available for powering the YSI 5200 should the primary power fail.
The YSI 5200 design incorporates FLASH Memory, RAM, and a battery backed-up real-time clock.
Should power be lost, none of the parameter setpoints or configuration data will be lost. However,
during a power failure, data in the data-log will be erased if no backup power is provided to the
unit.
Control Capability
The YSI 5200’s software gives it the capability for parameter control as well as monitoring. Using the 4
built in control relays, a wide variety of monitoring and control features can be automatically activated.
The sensors gather information and relay it to the YSI 5200 controller. The 5200 can directly control
devices through the four built-in relay outputs. Each device that the YSI 5200 controls, such as a heater or
chiller, can be programmed
Timing System
The timing control feature allows the YSI 5200 to control external devices such as a lighting system. The
timing system will support up to 4 independent control times per 24 hours. Each channel has one ON and
OFF time per 24-hour period.
Alarm System
The alarm system provides visual and audible notification in the event that a monitored parameter
exceeds the user defined range. Used in conjunction with the YSI 5201 modem (or a computer running
AquaManager software and equipped with a compatible modem), it provides remote alarm notification
