Premature "no contact" error between MC43 and MD3

We have a system that utilizes an MD3 inside the cab and a MC43 installed outside of our cab. Both are controlled by 2 separate relays to turn on power, one inside the cab the other outside. We are receiving a no contact error upon start up and we suspect this is because of maybe a timing issue of the 2 separate relays turning the modules on. Is there anyway to suppress the no contact error for a period of time at start up?
