- Page 6 Installation: The SST7200 & SST7400 have an integral latch on the rear of the device for installation on a standard 35 mm DIN rail. This device is OPEN type equipment that must be used within a suitable end-use system enclosure, the interior of which is accessible only through the use of a tool. The suitability of the enclosure is subject to investigation by the local Authority Having Jurisdiction at the time of installation.

The software is compatible with Windows XP, Vista and Windows 7 operating systems. The SST7200 & SST7400 must be connected via provided Dynalco P/N 270A-105574 serial communication cable.
- Page 11 RPM Signal The RPM Signal needs to be programmed prior to all other settings. The SST7200 & SST7400 are capable of accepting input signals from 2-wire (also known as variable reluctance) magnetic pickups as well as 3-wire (powered, TTL or hall-effect) type sensors.
- Page 12 Signal Lost The Signal Lost function is defined as the absolute maximum allowable period (time between input pulses in milliseconds) before an under speed relay is tripped. Similar to the Max Wave Duration described in the previous step, the Signal Lost setting is necessary for low speed applications where there is a programmed under speed trip.
- Page 13 Open Pickup The Open Pickup tab allows the user to select which relay (if any) will activate if an open pickup is sensed. Enable o Check this box to enable Open Pickup option Trip o Select either Setpoint 1 or 2 for the SST7200 o Select either Setpoint 1, 2 ,3 or 4 for the SST7400...
- Page 14 Analog Output The analog output tab is used to define the RPM range of the proportional 4 – 20 mA output. RPM Zero o Set to the RPM value corresponding to 4 mA output. o Normally set to 0 RPM but can be set to any value as long as it is lower than the RPM span.
- Page 15 Setpoints 1 & 2 (plus 3 & 4 for SST7400) The Setpoint tabs allow configuration of relay setpoints and relay logic. Enable o Check this box to enable each setpoint Relay Normal State o This is the normal relay state when not tripped o Either select normally Energized or normally De-Energized WARNING: For critical applications, it is highly recommended to configure the Relay Normal State as “normally...
