All features or combinations of features may notbe available on specific ATSs9B. Maintenance Selector Switch (MSS)Marked “OFF”, “ON”. This feature provides selectorswitch disconnection of control to transfer thus allowingtesting of the transfer switch control logic circuitry with-out initiating load transfer. Positioning the MSS in the“OFF” position isolates the control circuit, permitting man-ual operation of the transfer switch or testing of logic cir-cuitry without load transfer.14. Relay Auxiliary Contacts: This feature provides form “C”relay auxiliary contacts.14C. Source 1 Present: Provides four (4) normally open and four(4) normally closed contacts. The relay is energized whenSource 1 is available.14D. Source 2 Present: Provides four (4) normally open and four(4) normally closed contacts. The relay is energized whenSource 2 is available.15. Switch Position Indication ContactThis feature provides a contact that indicates if the powerswitching device is in the “Open” or “Closed position.15G. Source 1 Position Indication ContactThis feature provides 3 Dry Form “C” contacts that indi-cate the position of the Source 1 power-switching device.15H. Source 2 Position Indication ContactThis feature provides 3 Dry Form “C” contacts that indi-cate the position of the Source 2 power-switching device.18. MeteringThis feature includes all required external devices (CTs,shorting blocks, fuses, etc.) for a fully functional meteringsystem.18O. IQ Analyzer Normal (S1) Only18P. IQ Analyzer Emergency (S2) Only18Q. IQ Analyzer Normal (S1) & Emergency (S2) Switch Select-able18V. IQ Analyzer Load18R. IQ DP-4000 Normal (S1) Only18S. IQ DP-4000 Emergency (S2) Only18T. IQ DP-4000 Normal (S1) & Emergency (S2) Switch Select-able18U. IQ DP-4000 Load18AN. IQ 250/260 Normal (S1) Only18AE. IQ 250/260 Emergency (S2) Only18AL. IQ 250/260 Load18W. AmmeterA single ammeter is a true RMS sensing device that dis-plays single phase current only.The ammeter can be mounted on Source 1, Source 2, orload. The meter can also be configured for 1, 2, or 3-phasesensing by supplying one meter per phase for Source 1,Source 2, or load. Ammeters for both Source 1 and Source2 can also be grouped together.23L. 24 Hour, 7day, 365 Day Programmable Plant ExerciserThis plant exerciser has two channel electronic timeswitches with 365-day, 7-day, 24-hour programming. Eachchannel can be independently programmed and can provideup to 400 events. The plant exerciser offers daily, weeklyor annual programming capability with up to 99 separateholiday periods of any duration and priority. An LCD displayindicates load status, time-of-day, weekday and date.29G. Auto/Manual OperationThis feature provides 2-position auto/manual selectorswitch marked “Auto/Manual” which permits the selectionof automatic or manual operation. Once the selector switchis transferred to manual mode, manual transfer betweenNormal (S1) and Emergency (S2) can be achieved by oper-ating another 2-position selector switch marked “Normal-Emergency”.38. Stainless Steel Logic Cover38A. Stainless Steel Cover for Device PanelProvides an added level of security by providing a pad lock-able stainless steel cover for use with standard transferswitch device panel. The cover is designed for NEMA 1,3R, 4X, and 12 applications.38B. Stainless Steel Cover for ControllerProvides an added level of security by providing a pad lock-able stainless steel cover for use with standard transferswitch logic controllers and/or associated device panels.These covers function with Eaton’s ATC series logic con-trollers and device panels. The covers are designed forNEMA 1, 3R, 4X, and 12 applications.41. Space Heater With ThermostatThis feature provides a space heater and non-adjustablethermostat. External control power is not required.41A. Space Heater With Thermostat - 100 WattThis feature provides a 100 watt (W) space heater with anon-adjustable thermostat.49B. Sensing Isolation Transformer (Up to 600 VAC only)This feature provides 3-phase, 4-wire for Source-1 andSource-2 sensing input on ATC controller for a high resis-tance grounded delta system.
