Page 10: S49Ul System
6. S49UL System S49UL System Description: The MKS S49UL Thermal Management System is the 6th generation of MKS thermal product. The focus of S49UL is product Safety (UL Certification, improved insulation), simple and robust communications (out of box RS485 Modbus ready), and high temperature heating (200°C continuous). - Page 11 All interconnects within the system use custom hybrid connectors (Power + Signal). Because of the proprietary connectors to power the Series 49UL System a MKS supplied Power Kit is required. The S49UL Power Kit allows for power injection and communications pass thru, this feature allows for continuous communications on large or high-power installations that require multiple power drops.
- Page 12 The second kit terminates in a Type A USB and is intended for use with the MKS supplied Android App. The Android based user interface application is the only MKS supported S49UL software interface, no other MKS supported software is available at this time.

Page 13: S49Ul Installation
7. S49UL Installation The following guidelines are based on a typical installation of S49UL Thermal System, some installations could be different. Caution- The PTFE heater utilizes a fiberglass insulation. While the insulation is contained by the heater shell, use caution if shell is damaged. Caution- The internal surface of the heater (equipment contact side) may be hot. - Page 14 Unpack and verify that there is no damage to any of the heater jackets, controllers, or cables and accessories. If there is any question as to the quality or construction of the product contact MKS immediately. Installation area Inspection of parts and area to be heated for combustibles, sensitive equipment or parts that may be damaged by excessive heat.
- Page 15 Individual control devices are designed to be daisy chained together, however care should be taken to ensure the current draw on a single power adapter does not exceed 10 Amps. MKS provided power adapters use a 10 Amp slow blow inline fuse.
- Page 16 All S49UL interconnections are designed with a keying feature and positive twist lock engagement. When mating connections ensure the male and female connectors are properly aligned, axially rotate the male and female connectors while applying a slight lateral force to locate the keying position. Once aligned press the connectors together while turning the twist locking bale.
- Page 17 If the daisy chain nears 10 Amps of current draw, and there are still additional heaters to be connected to the system, an additional Power Adapter is required. Multiple Power Adapters may be used on a single Heater System or daisy chain line to add as many power drops as necessary.

Page 18: S49Ul Heater Controller
8. S49UL Heater Controller Controller Architecture: The S49UL Heater Controller utilizes single microprocessor control with a backup hardware safety. During normal operation both the Primary Control Circuit and the Hardware Safety Circuit are driven by the microprocessor. Downstream of the processor there are two power control relays wired in series, the series configuration provides both the Primary Control Circuit and the Hardware Safety Circuit the ability to directly cut power to the heater jacket. - Page 19 Wiring details The S49UL Heater Controller utilizes a hybrid power and communications interconnect cable. The cable contains the AC power delivery conductors as well as RS485 communications lines. The input and output connector pin outs for the hybrid power and communications line are shown in Figure 11 below.
- Page 20 Visual Indication The S49UL Heater Controller has two sets of LED indicators, the Status LEDs and the Diagnostic LEDs. Status LED’s are located near the heater jacket connection and provide indication of control status. Diagnostic LED’s are located towards the interconnect cable and provide information related to control alerts and errors.

Page 23: S49Ul Lta+ Controller
The S49UL LTA+ Controller provides a centralized Low Temperature Alert function similar to the MKS Series 46 and Series 48 Legacy LTA (Low Temperature Alert) module. When the S49UL LTA+ is connected to the heater network an addressing algorithm is automatically initiated. - Page 24 Once addressing is complete the S49UL LTA+ will begin polling the S49UL Heater Network querying each individual controller for its operational state and LTA status. If one or more controllers on the network reports an LTA condition, LTA active in the Error Register (See the Appendix) the S49UL LTA+ will generate an LTA condition.
- Page 25 Display Indicators The S49UL LTA+ Controller visual indication is limited to Low Temperature Alert status. The S49UL LTA+ will generate a Low Temperature Alert visual indication any time one or more heaters in the network is registering a local Low Temperature Alert. The S49UL LTA+ also generates a Low Temperature Alert visual indication anytime one or more heaters in the network is reporting a Current State other than Normal.
- Page 26 Process Control Output In addition to the Visual Indication, the S49UL LTA+ Controller includes a Process Control Circuit used to notify the user when one or more heaters in the networked system is reporting an LTA+ condition. The process control consists of three contacts labeled Normally Closed (N.C.), Normally Open (N.O.), and Common (Comm).

Page 30: S49Ul Basic Communications
11. S49UL Basic Communications General Information The S49 Controllers use Modbus RTU communications over a 2-wire serial interface Communications Settings: The communication data Rate is fixed at 115200 Baud Parity should be set to None Stop Bits set to 1 Each S49UL Heater Controller ships with a default Modbus Device Address of 246 Each S49UL LTA+ Controller ships with a default Modbus Device Address of 247 Two communications cables are offered depending on the termination type required. - Page 31 LTA+ Controller will resume polling the network and reporting the active network condition. The only supported MKS Instruments communications software interface is the S49UI Tablet Application detailed in Section 10 above. Direct connection to a PC, Laptop, PLC, or other Modbus Master Device requires the user to provide their own interface.
