Product Name(s): KMD-7001, 7002, 7003, 7004, 7051, 7052, 7053; TSP-5003, 5023
Product Description: The KMDigital VAV SCUs are application-specific controllers provided with on-board electric damper actuators for VAV terminal unit applications. They can operate stand-alone or communicate peer-to-peer when networked together. All have common VAV box control sequences pre-programmed and can be user-modified for custom sequences, or totally re-programmed for applications such as minimum outside air damper control based on actual flow measured.
Product Application(s): The following part numbers and descriptions outline the various specific applications for the KMDigital VAV SCUs. Specific I/O corresponding to these controllers are described in the next section. KMD-7001, 7051 - Single-Duct VAV Controllers are configured with all I/O needed to provide pressure-independent single duct cooling/heating; and time proportional or 3-stage reheat. These models differ only by the damper actuator used. KMD-7002, 7052 - Dual-Duct VAV Controllers are configured with all I/O needed to provide pressure-independent dual duct cooling/heating; and time proportional or 3-stage reheat. These models are to be used as the cold duct or master controller in a dual duct system, with the TSP500x units to be used as the hot duct or slave controller. KMD-7003: same as 7001, but with built in form A relay for fan, and triac for time proportional reheat valve control KMD-7004: same as 7001, but with built in form A relay for fan, and 3 stage triac for electric heat TSP-5003, 5023 - Airflow transducer/actuator

Additional Information
* Items in NV memory are not lost upon power or battery failure. Other types of NV memory such as EPROM, NOVROM, etc. do not directly impact system performance.
Can trend data be stored in this controller? Yes
How many total trend values can be stored? All VAV SCUs: Up to 2 trend reports can be stored consisting of 4 points per report.
What is the controllers role in trending? Programming resident within controller gathers and stores trend data on-board. Daily, or at set intervals (as operator selected), data is pulled by OWS from controller for archival.
Can controller be programmed to 'push' data to archive or are trends 'pulled' from controller?
When full, does controller automatically send up trend data, overwrite data, or stop logging data? If controller trend data buffer fills before being called by archive workstation, old data is overwritten.
Programming Method(s) The VAV SCU controllers come pre-programmed for their specific applications, but can be reprogrammed as needed. Programming uses a combination of fill-in template and characteristic pick bars for I/O point, virtual point (VARs), PID control loop, trend log, schedules, and runtime log definition. They use a non-proprietary (open) line-based programming language (ControlBASIC) for operating sequences.
Resident vs Non-Resident Program Execution Information not provided.

Automatical-Dial Alarm Support Available from controller using optional CommTalk DEM communications interface
Does controller perform multiple retries and buffer/store alarm until connection is made? Yes, via CommTalk DEM
Are multiple destinations possible? Yes, via CommTalk DEM
Upon controller power loss or hardware failure:
Are network communications affected? No, once the next network token-pass determines unit is offline.
Is loss recognized on/by the network and alarm reported? Yes
DO and AO response?
Outputs fail to a user pre-specified position
Outputs fail to a normal (unpowered) position
Outputs fail to last position
Other
Volatile memory functions?

Retained for life of backup battery
Other
Upon restoration of power does the controller:
Auto-reboot without operator intervention? Yes
Automatically reset/synchronize the clock? Yes. Use of at least one KMD-5801 or 5831, KMD-5210 'LAN Controller' or one KMD7xxx'C' Controller is required to reset clocks across the secondary network.
Update all monitored functions? Yes
Generate an alarm if backup battery is dead? Information not provided.
Upon network or communications failure does controller:
Continue to operate standalone? Yes
Operate with last global settings or user-specified value? N.A.
Do broken network segments continue to communicate within the remaining segment?
(Note: May depend on proper termination of segments for higher speed networks.)
Yes. When the secondary network is broken, a token-based peer-to-peer system generates a second token to operate the bus as two peer-to-peer systems.
Does network automatically reconfigure upon restoration? Yes, restored controller generates new token.
Does network store 'loss of communications' alarm with time of event? No
Additional Information (optional)
Self Test Diagnostics
Does controller have internal self-test diagnostics to check:
Processor failure? No
Internal hardware failure? No
Open/shortened sensor? Yes
Others? Short protection on outputs
Automatic, pre-programmed self-test diagnostics are not supported. Exceeded parameters and sensor error flags can be user programmed to set alarm.
