Accessory 72A Kit 755257-001 includes the above three items plus a 4-foot serial cable (629798-002) for a Power Manager. For G-design 7ATB, 7ACTB, and 7ADTB Automatic Transfer & Bypass-Isolation Switches, a 9-foot serial cable (629798-004) must be ordered separately.

Introduction

The ASCO Catalog 5110 Serial Module (optional Accessory 72A) is required with 4000 Series, 7000 Series, or Series 300 Automatic Transfer Switches (ATSs) for serial communications. With this option installed, the ATS Controller can respond to requests (from ASCO devices) to send the status of standard features and optional accessories. In addition, the controller can receive remote commands to control the operation of the ATS.

This manual explains how to install the Serial Module on 4000 Series, 7000 Series, and Series 300 ATSs only.

DANGER: Used to warn of high voltages capable of causing shock, burns, or death.

WARNING: Used to warn of possible personal injury.

CAUTION: Used to warn of possible equipment damage.

An experienced licensed electrician should install the Serial Module.

Installation

Mounting

The Serial Module mounts on a DIN rail directly under the ATS controller. See Figures 1 and 2.

1. De-energize both Normal and Emergency sources that feed the ATS. Then open the enclosure door and check with a non-contact AC voltage detector.
2. Mount the DIN rail (supplied in the kit) onto two studs (on the door) below the controller.
3. Install the Serial Module onto the DIN rail by hooking the top of the module on the top of the DIN rail and rocking it downward until it snaps in place. If you need to remove the Serial Module, pull the release tab underneath.

Figure 1 Description: Shows the Serial Module mounted on a standard 35mm DIN rail. The module has connectors labeled J1 and J2, and a terminal block labeled J4 with pins for COM, TX+, TX-, RX+, RX-. It also has indicator LEDs for POWER, RX, and TX. A 10-inch serial cable connects to J1.

Figure 2 Description: Illustrates the serial module connections to an ATS Controller (Group 1 or 5) and an Optional Power Manager. It shows a 9-pin D connector from the controller connecting to J1 of the Serial Module via a 10-inch serial cable. An optional Power Manager connects to J2 via a 4-foot serial cable.

Connections

A short serial cable connects the Serial Communication Module to the Controller. If a Power Manager is present, a long serial cable connects the Serial Communication Module to the Power Manager. Refer to the provided wiring diagram. Wiring must be performed by an experienced licensed electrician in accordance with the National Electrical Code and all local codes.

1. Install the 10-inch serial cable (from the kit) between the ATS controller receptacle (J7 on 4000 & 7000 Series, J4 on Series 300) and the Serial Module receptacle J1.
2. If a Power Manager is present, connect the 4-foot serial cable between Power Manager receptacle J5 and the Serial Module receptacle J2*. A 9-foot serial cable (629798-004) is required for G7ATB, G7ACTB, G7ADTB.
3. Prepare and connect the specified communication cable (Table A) to the Serial Module J4 terminal plug as listed in Table B and shown in Figure 3.
4. When daisy chaining multiple ATSs, the ATS farthest from the controlling device must have a termination resistor. The Serial Module has a built-in termination resistor that can be connected by moving two DIP switches to ON (see Figure 4).

Figure 3 Description: Shows the serial communication connections for the Serial Module's J4 terminal plug. Pin 5 is COM (shield), Pin 3 is TX+ (twisted pair), Pin 4 is TX- (twisted pair), Pin 1 is RX+ (twisted pair), and Pin 2 is RX- (twisted pair). Notes indicate using UL Listed, stranded, twisted pairs with overall foil shield for RS-422 wiring.

Setting the ATS Address

Set the communication address in the ATS controller. Follow either the 4000 & 7000 Series procedure or the Series 300 procedure below. Use Table D to record the address and other ATS information.

4000 & 7000 Series ATSs

1. Refer to Group 5 Controller User's Guide 381333-126 pages 2-8 and 2-9 for how to set a unique address for this Automatic Transfer Switch.
2. If ASCObus II protocol is used (such as with VPi computer software) and a Power Manager is included with the ATS, the Power Manager must be programmed with the same address as that selected for the ATS Group 5 Controller connected to the Serial Module.
3. However, if Modbus protocol is used and a Power Manager is included with the ATS, the PM must be programmed with a different and unique address (not the same as the address of the Controller). For setting the address in Power Manager Xp refer to Operator's Manual 381333-199.

Series 300 ATSs

1. Remove the cover from the controller by releasing the latch on the right side with your thumb. See Figure 5.
2. Locate DIP switch S3 (left center) and set a unique address for this ATS. Use a ball-point pen (or similar pointed tool) to slide the switch actuators left or right so that they match the illustration next to the setting (left=off, right=on). Recheck the setting. See Figures 6 & 7, and refer to Table C on the next page.
3. Reinstall the cover on the controller by hooking it on the left side and latching the right side.
4. The Series 300 ATS Group 1 Controller uses ASCObus II protocol. Therefore, if a Power Manager is included with the ATS, the PM must be programmed with the same address as that selected for the ATS Group 1 Controller connected to the Serial Module. Refer to Operator's Manual 381333-199.

Figure 4 Description: Shows DIP switches on the bottom of the Serial Module, used for setting the termination resistor. The switches should be ON for the ATS farthest away from the host device.

Figure 5 Description: Illustrates how to release the cover latch on a Group 1 Controller.

Figure 6 Description: Shows the location of the S3 DIP switch within a Group 1 Controller (Series 300 ATSs).

Figure 7 Description: Depicts how to set DIP switch actuators, with 'off' typically to the left and 'on' to the right.

Note: Address 00 is reserved.

Table D. Address Selection for each Automatic Transfer Switch with a Serial Module

Fill in the table below with the ATS Catalog and Serial Numbers and location next to the Address Number selected.

After all settings are made, close the enclosure door and reenergize the Normal and Emergency power sources to the Automatic Transfer Switch.
